For an easy tame, wait for the Lymantria to land and then place a tent directly where he/she is at. Its stuck until the tents durability dies out, this gives you enough to build a little house around it for a safe, easy tame.
With teamwork, it can be used to help tame other animals. One team member on Lymantria, the other ones shooting tranq. The slow effect is 90%, therefore, plenty to slow down any creature enough for a person to type it while shooting tranq shots.
Had a lvl 95 with 800+ health and a lvl 10 poison wyvern attacked and the moth was going to town, it didnt kill tge wyvern but it put up a hell of a distraction for me and my boys to get the stuff to kill it .......worth the tame tbh
Don't attack it unless u have a plan a good one is to wait for it to land, throw a normal bola at it, then shoot tranq arrows at its head until it passes out, then feed it mejoberries or any type of berries, you may want to build a house around it to protect you and the lymantria from storms
A lymantria can fit through a single ceiling tile space but an argentavis can't. Build a trap with one ceiling missing in the corner. Use a lymantria to aggro an argentavis, fly into the trap and out the hole, leaving the argentavis in the trap. Easy argentavis tame.
