Following some suggestions and being informed that it very likely could be possible to get vfx added to the pavise stance of deploying the shield I made an updated layout:
Pavise Crossbowman
Base Attack Bonus: +6
Feats: Shield Proficiency, Weapon focus - Any crossbow, Crossbow Sniper
Class feature progression
Hit die: 10
Skill points: 2 + Int modifier
Class skills: Craft trap, Craft armor, Craft weapon, Set Trap, Listen, Spot, Search, Lore: Arch-engineering, Lore: Local, Lore: History, Lore: Nobility
Base attack bonus progression: High
Saving throws high: Fortitude, Reflex
low: Will
1- Pavise Stance x1
2- Weapon Specialization - choice of crossbow
3- Pavise Stance x2
4- Rapid Reload
5- Pavise Stance x3
6- Rapid shot
Pavise AC+1
7- Pavise Stance x4
8- Manyshot
9- Pavise Stance x5
Improved Rapid Shot
10- Crossbow Sniper, Master
Pavise AC+1
Pavise Stance: The Pavise Crossbowman sets down their shield as portable cover in front of them. While deployed they cannot move from the spot they are holding, but gain a +4 bonus to dexterity, +2 constitution, and +2 bonus to saves. While deployed the pavise grants +4 shield bonus to AC, increasing by +1 at levels 6 and 10. A pavise crossbowman can use this ability 1/day at level 1 and gain an additional use every 2 levels beyond 1st level. Moving or equipping a weapon other than a crossbow cancels this stance.
Disclaimer: I am absolutely NOT an expert or even close to knowledgeable about power/balance in classes, so feel free to give all the constructive critisism/change ideas you'd like! Also I have absolutely no idea how hard these abilities and stuff would be to code....
-----------------------------------------
Some brief foods for thought:
- Split the Pavise Stance into two abilities 1) Deploy shield - grants the shield bonus while stationary and becomes a cooldown ability. 2) "hunker down" (Name is a WIP...) grants the stat bonuses as well as a haste effect (for an extra attack) used while shield is deployed, advances from 1-5 uses/day from class advancement.
- AC from the shield would base AC, not enhancement, showing the crossbowman's trained use as he advances in levels
