Okay, some things I have to say.
1- Summoner's Arc is another storyline upon defeating Karna Masta in the main storyline, where you (the person who has been summoning units to put into their squad, giving them imps, frogs and spheres to make them even more powerful) have to fight yourself for some time until you get the power to bring specific leveled units with you into your squad. Basically the summoner becomes a customizeable unit with 500 level cap. The 9.9x EXP effect of the cheats you have made doesn't effect the Summoner's Arc exp. To be honest, the level of your summoner doesn't do much, besides increasing your stats and also giving you a "weapon" with EX Skills that always boost your parameters, but unlike other weapons this black cloak that they call as a "weapon" has BB/SBB/UBB that deals Fire damage, instead of elemental damage based on the element of your summoner unit.
2- Yeah, Raid drops would be server-sided, so I don't think anyone can cheat them out.
3- As
@iAlex has said before, it is impossible to have No Energy Cost cheat along with x9.9 EXP cheat, and also Auto Win cheat along with x99 item drops cheat. The Energy/EXP cheats are connected to each other with coding, but I do know that in order to get drops from enemies, you have to kill them or open chests. So what Auto-Win does is that it skips all battles in the stage, effectively making it so that you don't get to open any chests or kill any creatures, making it impossible to get any drops, Zel or Karma.
4- If you plan to make an item injection cheat, then you might want to make it VIP or something, because the game would become super easy, and it would also make it really easy for Gumi to see if anything is wrong if people give themselves more than 1 of a specific item that they should only be allowed to make 1 of.
