I know that the summoner add +2 levels for each of the summons, and each of the summons abilities add +1 levels for each summons.
What I didn't know is that if my sovereign is a summoner (+2 levels) and I have another champion that has summon 1 ability (+1 level). It turns out that ALL summons have a +3 level (+2 from sovereign and +1 from the other champion).
Namely if I had 3 champions with summon 1 2 and 3 (+3 level summons) and a summoner champion with summon 1 2 and 3 ability (+5 levels) all my summons will be + (3*3+5)=+ 14 levels.
My question is this really intended?
