If i take a Mephit as my familiar (with Improved Familiar Feat).
Does the Mephit retain its ability to summon?
Also to be clear about the RAW:
1/day—summon (level 2, 1 mephit of the same type 25%)
Does the above mean that the familiar summons another familiar , and there is a 25% that the summoned familiar is the same type as the summoning familiar?
