I love you. Thank you for this.
I'm glad you like it! What do you think of the class itself?
Dunno. I don't like that it doesn't ever get better at using the swarms (more actions, I mean), but it's an interesting premise. (Except at the capstone, of course, but I don't think I've ever been within rock-throwing distance of a game that actually got to 20 or higher; and even then it seems abrupt.)
Also, you're missing a lot of stats for the Sliver Swarms themselves. Like size (Assuming slivers are medium, but a [Mob] can't be medium), AC, attacks and saves. So it's kinda unplayable at the moment (though, it being a WIP, I can understand why)
Gemhide Sliver should probably be Opaline Sliver instead - shroud seems more SR-y than [T]: Add mana does.
Okey doke. Need a new ability for Gemhide Sliver though. Actually, nevermind, I got it.
... I guess DR works. Not sure what would count as mana after all xD
Fungus Sliver could grant temp HP every time you deal damage to an enemy.
Well, I've already got Vampiric Sliver for that...
... Completely missed that. Hm, perhaps a Strength Of My Enemy-esque effect, then? Take damage, get some buffs?
Basal Sliver could have a "Sacrifice a swarm: Heal another swarm to full / resurrect a swarm that died this encounter" effect. (Because it coincidentally lets you sac for the amount of mana it takes to spawn a sliver); alternatively, this could be Darkheart Sliver (what with the sac-for-lifegain mechanic)
I'm hesitant to make any abilities which require sacrificing.
Take X damage, grant X temp HP to the Sliver Queen? Makes your swarms more fragile, to protect yourself... I really don't know what else seems black-y, other than sacrifice, considering it was a sac mechanic for black mana xD
Pulmonic could grant better fly maneuverability as well as having some sort of time-delay resurrection of swarms; perhaps after 3 rounds, a swarm is resurrected with very low HP (1/HD, maybe?)
Better flight (maneuverability) is good. Not sure about the resurrection though. It kinda conflicts with the idea of the Queen going crazy when one of the swarms dies.
Mn, I hadn't thought of that. "The effects granted by a destroyed Sliver Swarm persist for X round(s) after its death"? Reminiscent of the returning mechanic, but doesn't rez or otherwise impact things.
Sliversmith isn't a sliver. If anything, it would probably be a feat or a magic item. >n> Doesn't make sense to have the queen spawn a thing that is designed to spawn things originally designed to usurp the queen.
Hmm... I haz an idea
EDIT: Check out the new magic item! /EDIT
That looks very nice.
