I'm in the process of creating a character for an up coming high powered campaign, and I need some help. First off, the campaign is gestalt, but the first ten levels of one side of the build must be taken up with racial HD and LA the second half with Prc levels. This means the final build has to look something like: Class x +prc1 x//Racial hd z+ LA a +prc2 b, where z+a=10. I get the stats 18, 16, 16, 14, 12, 10 before racial mods and can be placed in any order. All books are open, except third party(but I may be able to get it with permission, if I need to.) I want to create a vermin based character that is some kind of spider based tauric creature. Vermin lord looks like a viable Prc and its hive mind ability will keep me up in power during the campaign. so far what I have is to use druid as a base, but I'm open to suggestions. It looks like the group will consist of just me and one other player who is most likely going to focus on support while I do most of the action, but that's how we like it. I'm thinking that I will need to cover offensive casting and melee. Ideas so far include using lots of summoned vermin for fodder and melee with spells like venomfire and other vermin buffs to cover 'offensive' casting. I do want the character to have a very heavy spider and to lesser extent vermin feel.
Right now I'm looking at using a medium vermin for tauric creature that way I will be able to have full mobility, as I expect this to be an Underdark campaign.
Edit: so far medium monstrous spider from srd//mm looks to be my best be for the creature part to tauric template
