So, if you want a front-liner to have this skill to break concentration of casting enemies, they actually do need Intelligence to make it effective. Intelligence influences Mental damage, including the skill Skull Knocker.Keep this in mind when equipping them with weapons. So you actually do want your damage casters to beef up their Strength score. Strength helps with the damage of your non-mental damaging spells, like Warstrike.Due to the opportunity system it's ok to have specialist characters who do most of the damage and others who sit in reserve and support them. Emphasize strength over most other stats for physical damage characters, include mages.

Level 30 may be possible but I have yet to hear of anyone actually hitting it.

Max level is somewhere between level 24 and level 28 or so depending on how much side content you do.The higher-level mage spells can be very potent but are a bit hard to use consistently due to high spell point cost - if you want to use the big spells, you'll need some way to boost SP generation (Best options are probably either a bard with the pipes tree or a vampiric source dagger). For mage spells, Fan of Flames, Conjuror's Mark, Crackling Bolt, and Arcane Barrage are all you really need (especially if coupled with Falkentyne's Fury).If you do not attack with weapon skills or if you plan on using artifact weapons (spectre snare, etc.) you may be better off not taking weapon skills and using elven weapons or artifacts as stat sticks. Therefore, If you attack with weapon skills you probably want to take weapon passives and use purchased weapons (bows, longswords, maces, etc.) for the skill bonuses they give.The same is true of most (possibly all) weapon skill passives they function off of skills, not actual weapons.Make sure you're using the right weapon for the skill, though - equipping a Long Bow helps Rain of Arrows, not Loose Arrow! You do not need to have that kind of weapon equipped to use a given weapon skill, but equipping a weapon may help use that skill - for example, you can use the "loose arrow" skill without a bow equipped, but equipping a short bow will let you use "loose arrow" more often. Weapons and weapon skills (including passives) are somewhat counter-intuitive.
