Oracle Elemental Weakness/CoC comet help

I would start with a better wand (with damage as extra instead of mana) and cast speed and headhunter instead of ingenuity.

You're spending a lot of little details on stuff that don't really give you much.

Your tree is wasting a ton of points on stuff that doesn't give you dmg, the more dmg you deal the more your CoC generates energy, so don't waste so many points on Energy generation nodes, use them on dmg instead.

your wand is also not that great, gain extra dmg is better, than a lot of other stats on the wand, like the 28% of crit bonus is not that crazy when a single node from a time lost jewel can give you 20%, mana is also not great on the wand.

Your chest also is quite shitty, you should aim to at least 45% life cost efficiency, you only have 1 good time lost jewel, like the normal nodes from the tree can give you more dmg than 2 of those jewels time jewels.

Your gems are also quite low lvl, and I'm not sure Tuls really work with embitter, all your gems should be 21.

get a sanctified wand with +6 skills while keeping other stats in par.

replace sceptre with one that grants discipline
