All increase damage by 15% I believe.
Fervent only works while all 4 fireteam are alive and stading
Stalker only works if your stamina is full.
Tactician only works if someone is trapped or interacting, meaning reviving or doing objetives, mudding too I guess.
Stalker is the best if you are gonna focus on shooting plasma from far, since plasma is the best weapon in the game, its the meta yes. Spear and bow do great damage with it, if you get someone trapped they are done, most ft classes will get down with 2 arrows, support with 3. 3 arrows to finish them while they are down. Best option for Elder.
Fervent is better if you want to try to get up close against the fireteam, like to do combi throws or some arrow shots, at least you have a better chance of getting the first kill due to the increase damage and you don’t have to worry about your stamina being full. I like to use on my 87’.
Tactician is very situational and you might not have the opportunity to use the extra damage but might be the best option for 97’. Can be usefull to give extra damage against field medics while they are reviving.
