Extensive testing in HotA led to two conclusions:
1. (which has been obvious for a long time) a rework is needed.
2. (less obvious) scrolls of levels 4-5 should be used in the same way as in SoD, only after building a guildhall of the corresponding level.
3. (for both versions) using animate and antimagic scrolls should require building a guildhall of level 3.
