What Fearless Roar does
Raises squad capacity by up to 15,000 for two hours.
Capacity beats percentages in a big fight. Save it for the marches that decide something.
Fearless Roar adds up to 15,000 squad capacity for two hours, so the Mighty Bison rides with the main march on the days when a bigger single march matters, such as garrison reinforcement or a decisive field fight.
Trigger it here:
- Before a Bear Hunt rally, so every march inside the window carries more troops.
- When you are the rally lead in Kingdom of Power and the extra capacity multiplies across the whole group.
What it costs to level
Every figure here is counted out of the full level table, so it is the cumulative Pet Food you spend to reach that level, rather than the cost of the single step.
| Milestone | Cumulative Pet Food |
|---|---|
| Level 15 | 12,075 |
| Level 30 | 42,275 |
| Level 100 (max) | 834,625 |
At level 100 the Mighty Bison carries a 33.52% troop attack and defense bonus and 2,413,440 power. That bonus applies whether the skill is on cooldown or not, which is why a pet you never trigger is still worth levelling.
Pet Food cost and the troop bonus are set by the generation, so two pets of the same generation cost exactly the same to raise. Their power and their skill are what differ.
Tips worth knowing
- The bonus scales with skill level, so a low level Mighty Bison gives far less than the headline 15,000.
- Great Moose is the rally capacity version of the same idea and stacks a different way.
Mistakes people make
- Firing it when you do not have the troops to fill the extra space.
- Using it on solo marches where 15,000 capacity does nothing.
