heavy or light armour isn't really a problem so we'll ignore points for that.
4+ Ward save is like the Ankhra so would be 45 points.
Mr2 Is like the Blue Khepra so would be 40 points.
+1 T now there isn't a TK version of this, but if we look at the example from the Dwarf book there's a rune the Master rune of Adamant that give the same and is worth 45 points.
Total worth 130 points on a Prince that can only have 50 points allocated to him.
I personally think it's over priced.
I've looked at the other books and have found the following items
- Dark Elf, Armour of Living death 100 pts, 5+ armour save with +1 W +1T
- Hordes of Chaos, Armour of tortured Souls 40 pts, chaos armour (4+ sv) +1 T against mundane attacks
- Empire Shroud of Magnus, while not giving you any T bonus it does give a 5+ ward sv and MR2 for 50 points.
- Ogre Kingdoms big name - mawseeker for 10 points +1 T
