Describe the suggestion you'd like
No self-damage using combo enchant.

Describe the reasoning for the suggestion. Balance? Fixing a frustrating mechanic? New Idea?
Combo enchant should be encouraged to deal damage multiple times, but the problem is, the more combos you do, the more lightning damage you'll receive, which discourages player from doing so.

Will this fix be backported to 1.18.2?

this bug was patched in verison 2.14.5

probably not
