You forgot one thing: you need 1 point in Bumba Lime, because it's a prerequisite for Cool Wabang Lime.
And 3 points in Rolling Rolling Thud? You do know that it's main source of damage is from your own melee damage, not the skill damage itself, right? So why put lv 3? It works just fine with lv 1.
And why max Sticky Jelly? You only use it for brief freeze on things, and lv 1 is just fine for it. AFAIK
, more skill level doesn't raise the freeze duration so anyting above lv 1 is moot point, unless you love to waste your mana.
And I'd get rid of Mana Potion, if I were you. At lv 1, it gives so little MP that it ain't worth anyone's trouble to even pick the thing up. Anything above lv 1, it costs reagents. Useless.
