Guild Wars 2

hi – just wondering if theres a skill that you can craft buffs – spells and med items for yourself and others….my last mmorpg i was biochem 400 would like to do it again if possible

Switch

Artificer makes monster type kill potions.

Chef makes foods that buff you in various ways.

For the foods you can also make trays/pots/feasts/… that can be shared with multiple people but they are not worth it unless you are going to be sharing them with 11+ people. The recipe items for those are also quite expensive.

Weaponsmith can make sharpening stones (+power) that stack effects with food

Artificer can also make tuning crystals

Huntsman can craft Maintenance Oil. While it says it increases power, it buffs precision (most likely a typo, as sharpening stones already increase power).
