Well, since this got moved I'll update it a bit more.

For sporeburst it looks like you tried to balance the fact that it is poison damage by adding some effects and increased area to it, and that all seems okay to me. But when you factor in the fact that in 4e there are a plethora of ways to change damage type this at will becomes ridiculous, just imagine a fire based teifling wizard that can use a fire version of sporeburst. Suddenly it becomes a ridiculously over powered at will. That's just my thought if it, so far looks like a cool concept.

[bloodshed343]

As far as I know, there's no way to change ongoing damage type. Also, it doesn't have a damage roll, and it doesn't pop minions. Overall, it's pretty much strictly worse than freezing burst. Actually, I might need to make it more powerful.

I don't claim to be an expert on 4e power design, but I do know one thing:

Don't make at-will powers (save ends). Just don't.

[bloodshed343]

Save ends ongoing damage is really weak. At level 30, this will do about 58 damage at most (assuming they fail three saves) or 90 damage over three rounds if spammed and everything hits. Freezing Burst will do 111 damage on average over three rounds if spammed and everything hits.

So you do less damage to more targets with a slightly better effect.

I'm changing it anyway to make the biomancer more of a leader whose buffs rely on inflicting ongoing damage.

Level 30 play is not a good standard to go by. Remember, many level 30 heroes were level 1 once, but how many level 1 heroes will reach level 30?

[bloodshed343]

At level 1, you do slightly more damage with a much worse effect.

[GPuzzle]

At level 1, you do slightly more damage with a much worse effect.

At level 2 you have a power that is guaranteed to deal 10 damage.

At level 11 you have a power that is guaranteed to deal 19 damage.

If you are a Half-Elf Conlock, suddenly 24+3d6 damage on all targets.

If you are a Half-Elf Palalock, bam, 36 guaranteed damage, and a save. At level 16.

And that's with basic optimization.

Also Half-Elf Knight with Sporeburst will be OP as heck.

Also, I recommend against using two different secondary stats. It'll make characters MAD and force them to choose between the two paths, at which point you might as well make two separate schools.

Fine, I made it all int/con. I was trying to balance the features assuming an even split in wis/con. I might need to tone down some features to account for a higher con mod.
