Thanks for the ino. Unfortunately i don't have Figher, but i have Valkyrie, Samurai and Ranger which have high Str, but nevermind then.
Btw i just wanna update my progress. Currently all my char are level 10,still training skill and magic at Arnika, manage to buy spell for my fearie bishop from Sadok and Kunar, but still haven't reach Crock, and still haven't went to Trynton. My plan is to train all skill and magic till reach 50-60 points, then i'll go to trynton. Most of instruments and gadgets that i can't use for now, keep in He'Li Bar. Some monsters are still beatable, especially when Savant Henchmen came out and killed my priest and ranger.

Edit: Btw, sorry for my slow progress as i have quite busy with piles of work to do, which i can't play W8 too often.

What weapon is your Valkyrie using? I highly recommend giving her a Stun Rod. (Earlier, the Lance (buyable from Anton in Arnika) would be a good choice if you had started from the Monastery, but you didn't so it's less useful, though it dies have a kill percentage).

Crock doesn't sell level 4 spells until level 11, but he does sell some other nice items, such as the Thieves' Buckler (+10 to Locks & Traps and Speed) and the Amulet of Life (requires 35 Artifacts, but casts Resurrection and is pretty cheap to have Lord Braffit recharge).

Yes, she is using stun rod, thanks to imported file, i didn't buy from Sadok. And yes, i bought lance for Vi.
For Samurai, i have him equip demonbane and wakizashi, and Hayai bo for his alternate weapon in extended range, and the reason of not using Bloodlust.
Well yeah, like i said i still haven't reach Crock, even though i can go straight to him, but i will soon after i finish Trynton.
