This began in 186, was in 187 and now 188.
The Pyrolizer tool does damage to the user. The TL80 does about 470-480 dmg to the user in one shot. You can kill yourself with it for shock value.
After a use, it sometimes is unusable.
After your first inject, if you leave the item out it will not fire. If you select a different item and try to re-draw the pyrolizer, you will get the warning 'You can not use this, yet'
Zoning or full relogging seem to both sometimes fix the tool so you can re-equip and fire again.
Since firing it is a bad idea in the first place, this at least helps keep someone from gibbing themselves from 100%hp on accident.
