Celtic Heroes

I know nothing about either of these two skills. Can someone tell me what the difference between the two and which is better? I know double shot is for rangers and double attack is for the other classes but what do they do etc.

Isent it the same skill?

Its a hit that does double the damage of a melee i think. the double attack is for all classes but a ranger cant use it if they use bows. thats were double shot comes in. its the same thing but for a ranger with bows. admin was trying to make a skill that all classes could use and they did a good job with this one

U mean almost all classes Mages and Druids are useless whit taht skill if they aren't like fully str Druid whit Ymir Totem
