Dragoneir Silent Gods: Once More Unto the Forest F2P
This video showcases how to defeat Once More Unto the Forest Stage 4 using no legendary heroes. While I do have the max attack% 5 hero affinity bonus, I only had it as 1/3 last week when I cleared it for the first time so it is not required by any means. Do not worry if you do not have as much enlightenment on Adolphus as I have. You should be fine with half of that. If you can get a legendary chest piece that has enlightenment, that should get you enough for the fight.
Positioning is everything. Either have all your heroes on the left or all on the right. This makes it so in the second phase only one of the 2 attacks hits. This gives you more opportunity to heal. Try to land an attack penalty debuff after the summons die before the dragon has a chance to strike you to soften the blow. Speaking of attack penalty, ensure you have enough accuracy to land it. If you need to run an accuracy chest to get the required accuracy, then do it.
