I dont see why Spirit as a shield has FCR FHR and resists, life gets +2 to all skills and only takes up to a Amn Rune.
Meanwhile Splendor gets +1 to all skills.
Spendlor gets 1-2 to all skills. Spirit as a shield gets +1 to all skills. So you choose between offense(skills) or defense like more FHR resists, life and FCR.
