Yeah, Fixx is right: Wrestling was nerfed, and I think it makes sense. While a "warrior Cleric" is a fun idea, it is dangerous for Clerics hunting in parties. Still, I do not think that will prevent Rosie and others from trying.
I accidentally got half of Fuoco's Wrestling on Nial, and it takes him ages to Wrestle a Harpie into fleeing. At least in full plate, the Harpie's doing less damage to him than he is to it.
Back on topic...I know for a fact it's possible for a Cleric to get LJ 10, but it requires fierce determination and lots of Strength Pots or Strength casts. Still, if a Cleric wants to go all "warrior Cleric" without using Sickles, it might be worth the 40-50 hour investment.
I still want to see a Cleric solo a SS. It's been done before.
