Questions on Tir na nog

[licker]

Well you can't use her indiscriminately obviously, but she does start with glamour and decent enough defense, she can buff with RL and mistform (if you feel the need), she can cast phantasmal warrior to spit out some chaff, ... Basically she has a higher cost in gold, but does not need any equipment to be essentially 100% effective against everything other than lightning immune, or giants.

There are tricks you can use, but against the right opponents they will have a difficult time countering her, and if you force your opponent to adjust to your tactics you are ahead of the game.
