Purchasing from other players is prohibited.
Level appropriate buffs, bind, and ports are allowed if you are in level range of the spell. Always make sure to donate.
Do not ask for buffs while grinding. If someone buffs you it’s fine. Click off buffs that are not level appropriate.
You may sell items at market value. No selling low lvl items like HQ pelts/Bone Chips for big plat.
Purchasing gear off vendors that they do not usually sell is prohibited. No looting other people's kills.
You may have an enchanter/cleric “Enchant” items for armor you make.
Buying research mats off vendors is fine. It is too hard to “farm” those specific items if you are doing research
And not specifically mentioned in the rules page but you must solo.
