these grenades dont even drop anything useful but except for the low lvl chars like the bomb arm which isnt even good. But i guess if you only fight it to die, watch it die, or whatever have at it ^^
i dont know why but its just fun to be a RDM and go and fight one of this since i just keep striking him with my sword and start casting water....he looks so funny when he dies falling on the ground
lol i just remembered a funny story about a pt i was in. it was 6 of us, each lvl 13 except for the BLM who was lvl 15, and we were going around killing stuff in la theine, doing pretty well. then we see this VT grenade, and so we confer with eachother and eventually we decide to attack it. but the rest of us, before we fight it, tell the BLM to be sure
NOT
to use fire spells, but we didnt know he was AFK at the time. so, he gets back, not knowing at all grenades are strong against fire, also not knowing we told him, and he starts out like this:
manafont, elemental seal, fire, fire.
we were really thankful the grenade didn't explode after the first fire, but then for some reason he did fire AGAIN, and that did it. the grenade self destructed, doing about 220 dmg to all of us. we all died except for me (galka MNKs have giant HP, ^_^) because of it. and afterward, i was the only one standing and i said, "well, this isn't the first time setting a bomb on fire killed someone!". we were all flaming him because we didn't know he was AFK. eventually he told us, but still, isn't it obvious that a bomb would be strong against fire? oh well, it was funny.
I fought one near the entrance to Jugner Forest, by the Crag of Holla. Took it out solo, as a 25 WAR/MNK. It didnt Self-Destruct, or use any specials at all, so I cannot say if it uses that ability.
