As some of you might know, I play a pacifist on the server. This means, that you refrain from killing mobs and try to gain positive alignment with every faction (except for Utumno and Huorns, which are hostile to anyone). You can do this by completing mini-quests, which do not always involve killing enemies, but also gathering supplies.
When it comes to Fangorn faction, you'll run into a difficulty: They don't give out quests. The only way to increase it, is to kill their enemies. So a pacifist could:
1) Raise your alignment with all other factions. Then kill enemies of Fangorn, which would lower your alignment to some factions. Do more quests for those factions.
This method works already, but it contradicts the ways of pacifism. Therefore I suggest one of the following:
2) Introduce mini-quests for Fangorn given out by Ents.
3) Or add another way of gaining alignment there: E.g. plant a tree sapling in Fangorn gives you +0.1 / +1 / +10 / +100 alignment there.
4) Or add another way, like performing a certain ritual there: E.g. digging an exact round lake of 100 blocks diameter, exactly 11 blocks deep, filling it completely with water, throwing in a certain flower at full moon, while 20 Ents are standing around, which results in Fangorn sprouting a very rare tree and even rarer flowers and give you +500 alignment to them.
The last one is a joke, but it could be something less complicated.
