looking at the ultimate magic book. my player is looking for some answered that i don't know how to answer as a dm, or should i say don't want to break the game without feedback
1. The player is playing a small character (a gnome, meaning he retains a 20ft land speed). His Eidolon on the other hand is a medium bi-ped (with 30ft land speed). The class ability called "Fused Eidolon" allows for the player to take on a form that receives the physical abilities of the Eidolon (str, dex, con) and the mental stats of the Eidolon ( int, wis, cha). The true question is, does the summoner pc gain a 30ft land speed while the Eidolon is summoned?
2. The feat Augmented Summoning allows summoned creatures to gain a +4 enchantment bonus to both Str and Con. does this also count for the Summoned Eidolon from its class feature.
3. since both the caster are the same monster/summoner, can casting a spell on the Eidolon or the summoner effect the combined summoner/Eidolon, such as by the spell magic fang, mage armour, so on and so fourth
