Technically, as long as you hit two times per click, any race has a theoretical cap of 51% if unhindered by Protection. Whether it be Elf Ranged Attack or Sword/Blunt dual-wielding.
Quote from Omegatronic;185154:
Can any mages out there tell me if Thunder works the same was for each of its lightning strikes? (It's the only other attack that I can think of that hits a target multiple times.)
For Thunder:
1 Critical in one click =
30% of happening
2 Critical in one click = 30% x 30% =
9% of happening
3 Critical in one click = 30% x 30% x 30% =
2.7% of happening
4 Critical in one click = 30% x 30% x 30% x 30% =
0.81% of happening
5 Critical in one click = 30% x 30% x 30% x 30% x 30% =
0.243% of happening
