I want to gain the overall manacost reducing effects on the eqippment and keep it up-to-date. For this i have to detect a swap of equipment since it might influence this reduction due to changing enchantment-effects.
"Onequipped" or "OnObjectequipped" events seem to be fitting for this.

First one is said to be buggy (stacking etc.) and i have to add a logic to determine the item which is swapped via skse and its slotmask (afaik). Huge amount of work, but if the events bugs don't kick in it will work.
But can I use the event without worries?

Last one refers to "Base Objects". Afaik these objects are pre-defined in the CK. So if i manually enchant an item, then use it, the event will trigger but if i check for the enchantment-effects on the "Base-Object" via SKSE-commands, will they be recognized (since the base-object is pre-defined in the CK, but the effects were added manually)? Do i understand the event correctly at all?
