Spells: Stacking of Major Shielding and Yaulp IV

[ApexNews]

there are a few weird ones, like
frostreaver's blessing:
1: Increase Hitpoints by 10 per tick
2: Increase Damage Shield by 10
4: Stacking: Block new spell if slot 5 is effect 'ATK' and < 1010
5: Increase ATK by 10
6: Stacking: Block new spell if slot 2 is effect 'Damage Shield' and < 1010

blocks divine barrier:
1: Invulnerability
4: Increase HP when cast by 16 (L29) to 1651 (L110)

looking in the history section of luc, apparently db had a damage shield until 2003
2003-08-26 10:31 Removed Slot 2: Increase Damage Shield by 25 (L29) to 36 (L50)

but it probably shouldn't matter because frostreaver's blessing didnt block it until 2003
2003-11-05 11:11 Added Slot 6: Stacking: Block new spell if slot 2 is effect 'Damage Shield' and < 1010

or maybe lucy just didnt know how to read that from the spellfile until 2003. who knows. bless ladyangel nilbog.
