I really like


How about making the Mobile Fortress a feat? Maybe gives the means to build the basic stuff and upgrades must be researched (a little like a wizards researching new spells).

As for mecharmor abilities, I have a few suggestions...

"potion launcher" : big barreled gun that shoot potions, does 1 damage on impact, plus whatever effect the potion has. Maybe multiple magazines for multiple attacks in a round. A final upgrade could be a "Mortar mode", launching several potions high in the air to rain down on the enemy. Maybe even add a vocation that permits fabrication of stronger alchemical stuff like improved Alchemist’s Fire or something.


Armor spikes : normal version and Flower of Death Macross Missile Massacre style

Elemental Hands : gives fists attacks with elemental damage (heat metal style), elemental damage could be added to the full armor later (think about it: red hot armor + grapple = Burning Bear Hug! Now add the armor spikes...)

Jump jets : give bonus to jump checks, could be improved to give lateral mouvement, giving dodge bonus during a round it's activated or during a charge.

Finally, for the capstone ability, how about being able to permanently sacrifice some innovation points to give Sentience to something?
