Trust me, at least a level 10 firewall is a must near the end of the game.

The great thing about fireball is that it does huge damage and has an area effect too. Nothing save bosses survives a fireball + firewall... but bosses are easily defeated by first using a high level magic blast.

A maxed out fireball with destruction does a guaranteed 3000 damage over 8 m. Maxed magic blast with destruction is insane with a guaranteed 5000 damage. Ideal against bosses.

As much as its not necessarily optimal, I'd like to throw a little credit to the "monk" style of play. I like to play "themed" characters when I can in rpgs, and I decided to invest in "unarmed" skill, I think that it is extremely underrated as "useless" its at least better than 1 hand sword. The percentages are beastly, and just leveling increases base damage. I also found out, you can were a shield, on your back, while being "unarmed". All I've seen is that the skill is just "useless" never any evidence why, sure, you don't get charm slots for it, and i don't know what the last rank % bonus is. but I'd like to see some evidence to why its disregarded. As previously mentioned the fast attack speed does not lend itself to skill attacks, which is why I've been taking advantage of passive warrior skills and buffs and the "priest" tree, eg; summon/mastery.
