Balanced dagger:
Absolutely. Looks like a really interesting item but I've only used it a couple of times in low-XP levels.
Gloves of Midas
Yep. Much as I love this item, CP value probably too high.
Venom Sword
Yep. I never use it.
Whurrgarbl / Martyr Wraps
Agree on whurrgarbl, don't have martyr wraps.
Strength Potion
Hm, I've been using it a lot lately but only on level 1 characters, where a trade of 10-11 mana for the same base attack is very useful. At higher levels it is pretty useless except as alch. scroll/trisword fodder.
