Yesterday me and my friend was doing some world PvP in TB so my HP got low and mana so I used a Lifegiving Seed which is food for people who are herbalism but it also changes you into a herb until you click the buff off..
So what happened was I ate the food and I was sitting there as a herb and a rogue sapped me then opened on me and I came out of the herb form but I noticed I still had my head down like I was sapped and when I walked my feet did not move...I was still in sap form even tho I was not sapped. I was walking like a zombie pretty much, when I casted spells I casted them with my head down and the motions were different and funny.
Futher Testing: Me and my friend later tested this in a duel and it would not work, so we thought about it for a while and then noticed after one of us won the duel we would either get on our knees because we lost the duel or cheer'd because we won the duel...that would cancel out being in sap form. I'm not sure if emotions would cancel out being in sap form but losing/winning a duel would cancel it out.
Step by Step guide:
1: Use Lifegiving seed
2: Rogue needs to sap you
3: either remove the herb buff or let the rogue open on you
4; You will now be in sap form but able to move and ect
Warnings: Winning/Losing a duel will cancel this out..not sure about emotions that have some type of movement involved. although you still can cast spells and take damage and the bug will not be removed.
Additional notes: This is not client side. and Lifegiving seed requires herbalism lvl 475.
