Troubleshoot grades, consumption, charged weapons and summon ammunition.
Equip a weapon that supports soulshots and use the matching shot grade. Consumption comes from the weapon, so one activation is not necessarily one item. A weapon-specific reduction chance may lower this amount. An already charged weapon does not consume a second identical soulshot charge; insufficient stock can disable automatic use.
Both ordinary and blessed spiritshots require the matching weapon grade and consume the weapon spiritshot count. Blessed spiritshots can be charged over ordinary spiritshots. The server can disable blessed spiritshots during Olympiad; this is a configuration rule, not proof that the grade is wrong.
Keep beast shots in the owner inventory and activate them through the owner. A living pet or servitor must be present. Consumption follows the summon soulshot or spiritshot count, not the owner weapon. Normal weapon shots are not a substitute for these summon handlers.
