Its total bonus is +22 on the following turn, and it will cap out at 100 within the next few turns – if it finally stops moving. It also adopts the Channeling stance, increasing it by a further +15, and is joined by a hero with the Magical Reserves skill, giving an additional +20% gain whenever the reserves are increasing. If it is a daemon-faction army, it will eventually start to receive debuffs – with the opposite true at the other end of the scale. It will have 40 reserves at the start of the next turn and will continue to drop the longer it remains here. Assuming nothing special happens, it remains that way.
It is in a region with Blowing Winds of Magic, providing +0 reserves per turn. A basic, early-game starter army begins with 50 reserves of magic.
