Lightning Strike ~ 5 Mana ~ 50 Bushido ~ (Attack)
(An attack with a large bonus to your hit chance.)
What it Does – This increases your hit chance by a large percent, and in effect, acts like hit chance increase jewelry.
* Hit Chance Increase : 50% Hit Chance Increase (caps apply)
Lightning Strike also has another function outside of the normal one provided above. It gives a chance at a critical strike, which is a direct damage attack that bypasses armor, delivering the full damage you are capable of to your opponent.
* Critical Strike Chance : (Bushido * Bushido) / 72,000
Example – If you have 100 Bushido and attempt to use Lightning Strike on a target, you have a 13% chance to do a critical strike. This critical strike will ignore any resistance the target has, delivering your maximum possible damage (this includes slayer, Damage Increase, Perfection, Enemy of One and any other applicable effects) directly to the targets Health Points.
† The damage from this critical strike is capped at 35 in player versus player situations.
100 =13.88%
105=15.31%
110=16.81%
115=18.36%
120= 20%
