pedido Trocar +1,+2,+3 por nomes nesse script refin [10 reps]

[gmstrikker 0]

Alguém poderia fazer isso pra mim? Mexer no meu sistema de refinamento trocar onde fica:

23:43 You see a katana +1 (Atk:19, Def:14 +1). It weighs 31.00 oz.

 

Por

23:43 You see a unc katana (Atk:19, Def:14 +1). It weighs 31.00 oz.

 

No caso só vai até +3, queria que muda-se por nome... Exemplo:
+1 = unc
+2 = rare
+3 = epic

 

Alguém poderia fazer isso p mim?

Pensei ser algo aqui:

 

 

self:setItemName(self:getItemName():gsub("(%s+)%+(%d+)", ""))

 

Mas não sei criar os ifs, não sei fazer
