Keep your expectations inside the game's limits
Decide how much to stake per spin knowing that the bonus round arrives at a rate nobody can predict in Bloody Dawn. How often free spins start is not known in advance. The result of one session is random, whatever the RTP. Two players with the same bet can finish a session far apart, one ahead and one at zero.
Look up which RTP version runs before you deposit, because the game rules are the only place it appears. The RTP describes the long-run return per bet, not the result of one session. It says nothing about your next spin.
Plan each session around the bet you can afford to lose, not around the top prize. The maximum win in Bloody Dawn is a ceiling that players reach very rarely. Treat it as the upper edge of the game, and let it set neither your stake nor your session length.
