1) Unfortunately there is only a BattleAutocastSpell no StartOfTurnAutocast.

 I want to increase movement on the map for units of a specific race by 1 for every x AirShards.

It is no problem to do it for all own units, but exclusively for some units need a final equation [UnitStat_xtraMove] * [UnitStat_raceflag].

It will work with an enchantment spell, but buffing every unit manually is far from the automatic solution I have in mind.

I solved it with an manually cast of an enchant unit spell.

While testing the spell I discoverd that the game rounds up the values of calculations.

0 - 0.12 = 0

>0.13 = 1

Very strange.
