Upcoming Spring is Coming Event of 2022

Having a question about the upcoming event, please post it here instead of asking me directly in game.

Changes added compared with the previous Combat Events:

+ Increased Warhorse damage.
Just like with the regular combat, a warhorse equipped with horseshoes will now deal additional damage when successfully hitting the Winter Bandits. The extra damage is a random value between the minimum and maximum damage from horseshoes (which currently is 1 - 2).

+ The Bravery Skill replaced the Cowardice Skill effect.
With each attack there's a 10% chance a "Bravery roll" is required. The chance to trigger such a roll is equal for all Seekers and isn't modified by any skills. If the Bravery Test is required, the Seeker must have equal or more on their Bravery Skill than a random dice roll (1-100). If the test is passed, nothing happens. If the test fails the total damage of that attack will be reduced by 30%. Seekers who fail their test will see their Bravery Skill increase.

If I understand it correctly the bravery test fail reduces damage by 30% but raises Bravery skill - is there any additional stamina involved or other penalties to that attack? The locations based bravery tests need additional stamina to attempt entering so thought it best to ask  Thank you in advance

Personally I think the damage penalty is too high and it affects mostly newer players who need now to hire the bravery follower or do a good start on Bravery to have more chances to get prize points - which was not the case as much with cowardice
