1. Your summoning doll will NEVER gain experience points from battles (even if it has the final kill). If you want to upgrade your doll, you'll have to invest your own skill points in order to do it.
2. Always remember that you CANNOT unlearn any of the skills in the summoning skill tree.
3. For a higher radius for your summoning dolls, invest points in summoning dolls->specials->extra radius.
4. For further explanations about summoning dolls skills, see
