Doesn't anyone think there should be a sun spell called reinforce/strengthen shield? I think it would complete the set of lvl 86 sun spells quite nicely, not to mention those avid tower shield spammers in pvp xD
Interesting thought, but I would be wary of a spell that adds a fixed percentage. Suppose the spell adds 10% to the damage reduction. If you throw this on a tower shield, the result is kind of meh, increasing the reduction from 50% to 60%. Throw it on a spell card 85% shield, like the ones given by Greebly's gemstone, and you increase the reduction from 85% to 95%, which is pretty awesome.
Perhaps the spell could increase the damage reduction to halfway between the shield's base value and 100%. So a tower shield would go from 50% to 75%, or a school double shield would go from 70% to 85%. The effect on weakness would be pretty extreme, though, going from 25% to 62.5 %.
Edit: reflecting, it seems my comment about weakness is ill-considered. Weakness is not actually a shield, but rather a negative charm thrown on the opponent.
I would definitely agree with the OP and Dayrider. I would love to see a Sun Enchantment that effects Shields and Debuff spells.
Reinforce Shield sounds like a good name and gives +10% to 1 positive Ward spell.
Ailing Sickness is a name I like for debuffs. So +10% to 1 negative Charm spell.
On top of those spells, I think Simplify and Elucidate should be readded as spells to train in worlds after Celestia (Zafaria and Azteca are good places). I'd also like a Sun enchantment that allows you to place 2 enchantments on 1 spell, excluding the enchantment that allows this effect.
So something like Radiance- Allow 2 enchantments on 1 spell. Then someone could could place spells like Colossal and Extraordinary on 1 spell. Or maybe if Simplify and Elucidate were re-added, they could simply be given a second effect that allows a second enchantment to be placed on the spell. Just a thought.
