Hi! I am really sorry if it is not okay to ask here, but I very need to hear the answer🙏

Is it okay to have these enchantments in pickaxe? I mean it's a strange a little. Btw, I use Sinytra. Can you answer me will these enchantments work properly? Maybe I could take it offhand or how would it increase damage from fire? Excuse me again🙏

Definitely not okay.
Although, enchantment conditioning may be easily broken by other mods, so it is likely that not Sinytra is the cause, but other mods.
