Mobility

Mobility is an armor stat. It determines movement speed, initial jump height, and Hunter class ability cooldown. It is similar to Agility of Destiny 1.

Mobility Tiers

All armor stats provide benefits in tiers, capping at tier 10. Armor stat Tier can be calculated with the following equation:

Mobility Tier	0	1	2	3	4	5	6	7	8	9	10
Dodge Cooldown	0:34	0:32	0:30	0:29	0:26	0:24	0:22	0:19	0:16	0:14	0:11
Movespeed Increase	0%	4%	8%	12%	16%	20%	24%	28%	32%	36%	40%
Movement Speed
Sneaking(m/s)	2.75	2.86	2.97	3.08	3.19	3.30	3.41	3.52	3.63	3.74	3.85
Strafing(m/s)	4.25	4.42	4.59	4.76	4.93	5.10	5.27	5.44	5.61	5.78	5.95
Walking(m/s)	5.00	5.20	5.40	5.60	5.80	6.00	6.20	6.40	6.60	6.80	7.00
Sprint(m/s)	8.00

Notes:

• Mobility does not affect sprint speed.
• "Strafing" is side-to-side motion or back-pedaling.
• "Walking" is forward motion only.

Changing Mobility

The primary source of Mobility is from a player's armor. There are multiple options to increase Mobility.

Mods

Mods form the primary way to increase mobility outside of intrinsic armor stats.

Mod	Mobility Increase
Mobility Mod	+10
Minor Mobility Mod	+5
Mobility-Forged*	+3

* Requires the Artifice Armor perk to drop before the mod can be socketed.

Perks

Some weapon and armor perks conditionally grant increased mobility. These buffs usually do not mention the exact numbers regarding mobility increase. Instead they will opt to mention that it grants "increased mobility" or "increased movement speed". For this reason, exact numbers can only be acquired through community testing and these arcane buffs are commonly called "hidden mobility" or "invisible mobility".

Mobility granted this way behaves exactly like mobility granted by armor and mods. This means that movement speed and dodge cooldown is affected. Players should consider this when creating a build for a guardian that relies on mobility so as not to waste the stat buff. For example, if a Lightweight Frame weapon is in use, a guardian with 80 mobility can reach 100 mobility while it is readied. These buffs stack additively with each other.

Below are some examples of hidden mobility buffs

Perk	Mobility Increase
Lightweight Frame	+20
MIDA Multi-Tool	+20
Wraithmetal Mail	+50

Fragments

Certain Fragments can increase Mobility while others can decrease Mobility.

Fragment	Mobility Changes
Echo of Dilation	+10
Echo of Persistence	-10 (Hunters only)
Spark of Focus	-10 (Hunters only)
Thread of Ascent	+10

Movement Speed

Mobility affects movement speed. Player movement can be divided into 5 categories: Sneaking, Strafing, Walking, Sprinting, and Jumping. Movement modifiers may apply some or all of the categories.

Walking

Walking refers only to forward movement while standing, but sprinting. Side-to-side motion and back-pedaling is not subject to walking speed and is instead classified under strafe speed. Base walking speed is derived from mobility and increases by 0.20m/s per tier of mobility.

There exists 2 buffs which apply to walking speed:

• Lightweight Frame: +20 Mobility, +6.25% Walking Speed, +6.25% Sprint Speed
• MIDA Multi-Tool: +20 Mobility, +10% Walking Speed, +10% Sprint Speed

Mobility Tier	0	1	2	3	4	5	6	7	8	9	10
Mobility Bonus	0%	4%	8%	12%	16%	20%	24%	28%	32%	36%	40%
Walking (m/s)	5.00	5.20	5.40	5.60	5.80	6.00	6.20	6.40	6.60	6.80	7.00
Lightweight Frame (m/s)	5.74	5.95	6.16	6.38	6.59	6.80	7.01	7.23	7.44	7.44	7.44
MIDA Multi-Tool (m/s)	5.94	6.16	6.38	6.60	6.82	7.04	7.26	7.48	7.70	7.70	7.70

• Movement speed from mobility and movement speed from external bonuses stack together multiplicatively
• It is possible that walking speed has a hard cap of +12.5% for external walking speed buffs.

- This would imply a walking speed hard cap of 7.88m/s.

- Assassin's Blade and The Scientific Method may provide this 12.5% walking speed buff, but this is yet to be tested.

Sprinting

Mobility has no effect on sprint speed but there are a number of buffs which do increase sprint speed. Sprint speed is capped at +12.5%.

	Speed(m/s)	Sprint Speed Bonus
Base	8.00	0%
Weapons
Lightweight	8.50	6.25%
MIDA Multi-Tool	8.80	10%
Lightweight/MIDA Multi-Tool + any bonus	9.00	12.5%
Armor
Dunemarchers	8.50	6.25%
Peacekeepers
Transversive Steps
Frost-EE5
St0mp-EE5
The Dragon's Shadow
Subclass Perks
Keen Scout	8.50	6.25%
Focused Breathing

The community will often mention "stacks of sprint speed". This refers the the +6.25% boost that most sprint speed buffs fall under. It is widely held belief that these sprint speed buffs stack together to a cap of 2 stacks (12.5%) This is a misconception and the actual behavior is more nuanced. It is correct that the sprint speed cap is +12.5% (9.00m/s), but sprint speed buffs do not stack. There are only 2 exceptions to this rule: Lightweight and MIDA Multi-Tool. The misconception arises because lightweight weapons are a common use case and do not trigger a conflict with another sprint speed buffs like St0mp-EE5. Other than these 2 exceptions, combining sprint speed buffs will only result in the largest of the sprint speed buffs being applied and the others ignored.

Strafing

Strafing encapsulates all side-to-side motion as well as back-pedaling. Strafing is 85% as fast as walking but does not derive its speed from walking. This means that movement speed buffs that affect walking do not affect strafing. Notably, Lightweight and MIDA Multi-Tool do not affect strafe speed.

Mobility Tier	0	1	2	3	4	5	6	7	8	9	10
Movespeed Increase	0%	4%	8%	12%	16%	20%	24%	28%	32%	36%	40%
Strafing(m/s)	4.25	4.42	4.59	4.76	4.93	5.10	5.27	5.44	5.61	5.78	5.95

Sneaking

Sneaking encapsulates all movement while crouched and derives its movement speed from walking and strafing speeds and so it benefits from any buffs which apply to those types of movement. Notably, Lightweight and MIDA Multi-Tool which apply to walking movement, are inherited while Sneak-walking.

Mobility Tier	0	1	2	3	4	5	6	7	8	9	10
Movespeed Increase	0%	4%	8%	12%	16%	20%	24%	28%	32%	36%	40%
Sneaking(Walking) (m/s)	2.75	2.86	2.97	3.08	3.19	3.30	3.41	3.52	3.63	3.74	3.85
Sneaking(Walking) + Lightweight (m/s)	3.16	3.27	3.39	3.51	3.62	3.74	3.86	3.97	4.00	4.00	4.00
Sneaking(Walking) + MIDA Multi-Tool (m/s)	3.27	3.39	3.51	3.63	3.75	3.87	3.99	4.00	4.00	4.00	4.00
Sneaking(Strafing) (m/s)	2.34	2.43	2.52	2.62	2.71	2.81	2.90	2.99	3.09	3.18	3.27

• Sneaking incurs a -45% movement speed penalty relative to post-buff walking speed and strafing speed.
• Sneaking speed has a hard cap of 4.0m/s; no amount of buffs will break this.
• Transversive Steps and Keen Scout from Way of the Trapper both increase sneak speed to the hard cap of 4.0m/s.

Aiming Down Sights

Aiming Down Sights incurs a -25% movement speed penalty to all player movement. This penalty is applied on the player after all other buffs and penalties are calculated so buffs like Lightweight will still apply to ADS-walking Speed. Sidearms apply a lesser penalty of -15% to aiming down sights.

Mobility Tier	0	1	2	3	4	5	6	7	8	9	10
Mobility Bonus	0%	4%	8%	12%	16%	20%	24%	28%	32%	36%	40%
Normal (-25%) (m/s)
Walking	3.75	3.90	4.05	4.20	4.35	4.50	4.65	4.80	4.95	5.10	5.25
Strafing	3.19	3.32	3.44	3.57	3.70	3.83	3.95	4.08	4.21	4.34	4.46
Sneaking(Walking)	2.06	2.15	2.23	2.31	2.39	2.48	2.56	2.64	2.72	2.81	2.89
Sneaking(Strafing)	1.75	1.82	1.89	1.96	2.03	2.10	2.17	2.24	2.31	2.38	2.45
Sidearm (-15%) (m/s)
Walking	4.25	4.42	4.59	4.76	4.93	5.10	5.27	5.44	5.61	5.78	5.95
Strafing	3.61	3.76	3.90	4.05	4.19	4.34	4.48	4.62	4.77	4.91	5.06
Sneaking(Walking)	2.34	2.43	2.52	2.62	2.71	2.81	2.90	2.99	3.09	3.18	3.27
Sneaking(Strafing)	1.99	2.07	2.15	2.23	2.30	2.38	2.46	2.54	2.62	2.70	2.78

• Moving Target reduced the ADS movement penalty by 2.5-3.5%(requires testing for exact number).

Jumping

Initial jump height is affected by Mobility. Jump abilities do not benefit from this bonus. Buffs which give hidden mobility will benefit jump height up to the 100 mobility cap.
