I'm all for tweaking the blink dog flesh, telecontrol is very strong even from the ring.
playing with the script folder past few days.. this perma-state 'feature'|superbug is very useful and outright OP at times
A character who I play often Loves INT, after a while in the lower GC he happily gains perma Telecontrol and ESP, along with his love of Intelligence, newfound TeleControl + stack of Wands of Teleport, he may blink endlessly around, while finding any threats. (ESP should scale with PER)
Like Polyitis and Teleportitis, ESP(ESP-ing?) gained natural could/should activate every few turns(think Detecting Status) . The higher your ESP/Telecontrol, the longer you can have it in effect. Amulets being Permanent by wearing need not switch off every so often.
to remove the bug would spark hell for the lovers and haters. To address some of the strategies we've developed around this emergent feature or NERF it a tad (now 3 Floating eyes, say 5 instead) and allow a chance/event to remove it. 'You ate some mutated blink dog flesh'[ you may NEVER have telecontrol ever again..']
