Although our group has not reached 13th level yet and are not particularly close i thought i would have a look into building a large as possible synthesist summoner, just for the fun, i have come across a few of questions though:
At 13th level i will be taking the Huge evolution for my eidolon and possible even be casting enlarge person on him (quadruped)
1- with the huge creature evolution can he choose to be smaller or is he always huge without reduce person? (this could be a problem getting into buildings/caves etc..)
2- with the appearance of the eidolon being any fantastical creature could i make its huge/gargantuan appearance longer rather than taller? (i dont see why not, just wanting clarification)
3- with a synthesist, how does he look while within his eidolon? does he have to walk around on all fours if the quadruped eidolon the same size (medium @level 1-8) was described as a wolf like creature? (purely for the appearance of walking through towns)
4- assuming the eidolon has a starting weight of a normal medium creature, (i have roughly assumed 100kgs/220lbs) when he gains a size increase (unless im wrong) the eidolon would be 2x height & 8x weight? do that again for large-huge and then huge-gargantuan and you end up at roughly 51000kgs/110000lbs.. and 40-50ft tall.
the question being: are there rules for if something like this creature fell/jumped/stood on any other being? what kind of damage would that incur? and what kind of saves? (i found the cave in damage but it would probably weigh more and be harder to get out of)
thanks in advance
