Changed adventure map movement formula

Creatures with low movement were useless not only in combat, but also on adventure map because they slow down your army. Fast creatures on the contrary make your army significantly faster, so after playing Heroes 4 for a while you start ignoring creatures like trolls, earth elementals etc.

Enhancement Mod changes adventure movement formula to reduce difference between slow and fast creatures: maximum movement limit remains the same of 30, but minimum increased from 12 up to 20!

New adventure objects

Phylactery Forge: Grants visiting heroes Immortality.

Fountain of Venom: Grants visiting heroes Poison Attack for one battle.

Fountain of Bless: Grants visiting heroes Bless for one battle.

Sparkling Fountain: Reduces cost of visiting heroes spells by 2 for one battle.

EM 1.2 also supports objects from H4 Object Package by Karmakeld and Equilibris 3.55 (including artifacts). It’s more than 200 new objects!


Lots of bug fixes and QOL improvements to make Heroes 4 even better.
