Dota 2 damage reduction 10silver
Damage manipulation
There are several ways to affect the final value of a damage instance. Damage can be manipulated on both ends, from the dealing unit (outgoing damage) and the receiving unit (incoming damage). Armor and magic resistance are the most common damage manipulators, affecting incoming physical and magical damage respectively (no similar trait exists for pure damage). They usually reduce damage, but can also amplify it if their values are negative. Spell damage amplification is the main trait for amplifying (but not for reducing) outgoing spell damage (no similar trait exists for attack damage). Besides these, there are some other ways to manipulate damage, ranging from amplifying damage, reducing damage and even negating damage completely.

Sources of damage manipulation [ edit ]
Amplifying incoming damage [ edit ]
Damage amplification causes afflicted units to take additional damage.
Besides these, other ways to amplify damage is by reducing armor for physical damage or magic resistance for magical damage.
Amplifying outgoing damage [ edit ]
Besides spell damage amplification, these abilities amplify outgoing damage.
Reducing incoming damage [ edit ]
Just like how damage can be amplified, it can also be reduced.
Besides these, other ways to reduce damage is by increasing armor against physical damage or magic resistance against magical damage.
Reducing outgoing damage [ edit ]
These abilities are able to reduce outgoing damage.
Stacking damage reduction & amplification [ edit ]
Armor and magic resistance work separately from other damage manipulators. This means they always stack multiplicatively with any other listed ability.
Bes > Borrowed Time ‘s aura, Ghostship ‘s rum and Mana Shield , all damage reducing and damage amplifying effects stack additively with each other. Borrowed Time, Ghostship and Mana Shield stack multiplicatively with them. Mana Shield also stacks multiplicatively with Borrowed Time and Ghostship. However, the damage reductions of Borrowed Time and Ghostship do not stack with each other, although both still react on the damage (Borrowed Time still heals Abaddon, and Ghostship’s rum wear-off still counts the damage). The damage amplification which illusions usually have stacks multiplicatively with all other damage amplifying and reducing effects (considering they are able to affect illusions).
Examples of additive stacking (all values consider highest possible value, examples ignore armor and magic resistance, 100% is the base value):
100 + 30 + 35 – 1.2 = 163.8% damage
100 – 22 – 40 = 38% damage
100 – 80 – 1.2 = 18.8% damage
100 – 100 + 30 + 36 + 35= 101% damage
Examples of multiplicative stacking:
(100 – 1.2 + 35) * 40% = 53.52% damage
- Medusa affected by the same as above, but also additionally by Ghostship takes:
(100 – 1.2 + 35) * 40% * Expression error: Missing operand for -.% = Expression error: Unexpected
- A Conjure Image illusion (taking 400% damage) affected by Overcharge and Stampede ( ) takes:
(100 – 1.2 – 40) * 320% = 188.16% damage
Stacking outgoing damage manipulation stacks in the same way as incoming damage manipulation, i. e. additively. However, since incoming and outgoing manipulations happen at different times (outgoing happens first), they stack multiplicatively with each other.
Damage negation [ edit ]
Damage negation causes entire instances of damage to deal no damage to its target, however, the instance is still registered. This means, if something reacts on damage without having a minimum damage threshold, it still reacts on the negated damage.
