Myrokratios: Also you should check the manual for tables, which list which skill ranks every class can achieve. Not everyone can become grand master in every skill they can possibly learn. For example, knights, thieves and clerics can learn bow, but only Archers can become GMs in them. Just as only thieves can become GM in Disarm Traps. I learned that the hard way (as in, after I gave my thief, instead of my clerice, the Merchant skill), which is one of the reasons I started over today.
Thiev: BTW, remember to open containers with a party member that has this skill ;)
Myrokratios: And buy/sell stuff with the party member that has the Merchant skill (if any of your characters has that one). I always have trouble remembering that.
ALL pary-memebers can get mechant, and I would recommend to get that as soon as possible for all. But only the Cleric can get GM in it. BUT: you not oly sell and buy items at higher/lesser rates, but also learn new skills at lower costs. Rank-upgrades, however alsways cost a fix price depending on the skill and rank.)
Same goes for the learning-skill. All party-members can get learning. And 1 point alone gets a 10%-bonsu for every experience, they get. (so I normaly don't level learnig past 1, except for the druid, maybe. I always take a druid in my party.)
BTW: high perception is also a way to avoid trap-damage. If a member has high perecaption, he just might dodge the trap and get no damage at all.
And the third way to handle chest-traps is the telekinesis-spell. But be carefull: although the graphic of the traps suggest, that they are just melee in reach, they realy have a far reach. You should stand as far away as possible, if you're about to open a chest with that spell.
Edit: since there doesn't seem to exist a spoiler-format in this forum, only continue to read on your own risk

I would recommend to get that fireball-wand at the beginning. But DON'T accept it from the NPC, but kill and rob him. (He deserves that!) You even can lure the dragon-flies to do that... Or you must face some consequenses later on... ^^
If you have that wand, just equip it like a weapon. BUT: you ALWAYS will use the wand, if you have it equiped, also if you have a bow or a second weapon in the other hand. So, you alway will use a charge, and, if you stand too close to an enemy, the explosion will damage your entire party. The game has a non-deactivatable friendly fire for aoe-spells like fireball. So I would just equp, fire, and de-equipt it again to save charges and to avoid using it by accident. [/spoiler]
