## Notes

* If the attack is a normal  critical strike it will deal 160% of the enemy's AD, instead of 200%.
	+ If the enemy also has **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**, it will deal 180% of the enemy's AD, instead of 225%.
* **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**, and **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** are the only items that can reduce  attack speed.
	+ The attack speed slow on **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** and **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** do not stack with each other, however they do  stack multiplicatively with **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** for a combined 27.75% attack speed slow.
* **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).**  critical strike damage reduction against abilities only applies for those that act like a basic attack (i.e **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**) and those that grant modified damage (i.e **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**). It doesn't apply for those that only deal **bonus** damage (i.e **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**, but note that it still applies for the base damage).

## Strategy

* **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** is a strong counter against basic attackers that stack well on  Critical strike chance, like **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** and **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).**.
