Bonuses can derive fromErf-b1-p125:
Assuming that Wanda is level 8 or 9 and Ansom is level 10, with Summer update 33, then the bonuses listed could be arrived at with these formulas.
Chief Warlord bonus
Stack: Base Magic Bonus (Possibly Level)
Battlespace: BMB/5-8, or non-variable 1.
Ansom's bonuses were:
Stack: +10 (His level)
Hex: +5 (His level/2)
Battlespace: +3 (His level/3, rounding down, or level/4, rounding up)
Wanda's bonuses were:
If she is level 8, that would mean level, level/2, and level/8 or /7,6,or 5 rounding down.
If she is level 9, that would be level-1, level/2 rounding down, and level/5-8 rounding down.
If she is level 7, that would be level+1, level/2+1, and level /7 or level/8 or more rounding down +1
In any of these cases, the 1 may be an arbitrary 'static' bonus for the battlespace independent of the others.
Parson gave a bonus of +2 to all units in Gobwin Knob. This is included as the capital bonus.
Artifact and Stack
The weakest unit in Ansom's stack had an attack of +30 and a base attack of at least 6. The total Warlord and Caster bonus was +18. This means that there is at least +6 remaining.
This would include the Artifact and stack bonuses. In addition, every unit in the column had a base attack of 6+. Those in Ansom's personal stack would undoubtedly have higher base attack than that.
