Royal thorns, have they been mentioned?

[BB Shockwave]

I always found good quantities of them on the big main island (forgot the name right now). Even used them for a while, but since I was going for no loss as a warrior, and got Time Back only late in the game (and Sacrifice doesn't really work for a warrior due to low magic stats) I dropped them later.

Also, sadly there are a lot of fire-using enemies (Fire Dragonflies, Imps, Demonologists, Alchemists, red and black Dragons) that will most assuredly pick on your royal thorns. Summoning weaker thorns helps, but since they are so slow, they always get to act after these fast enemies.

That said, I still value them more then the Gobot-spawning Chosa. Those cannot do anything when they are not adjacent to an enemy. Royal Thorns can at least move, and with haste they can even move and shoot in the same turn. They also have a very strong attack even at melees range.
