Herumon Tower is a climb: fight the creatures on each floor, open the portal, go up. This guide takes you from the sign-in screen to your first fight.
Sign in through Steam (1), Google (2) or Discord (3). Your save lives on the server, so the same sign-in brings the same climb back on any device.
The tower asks your age once (1), then the button under it (2) takes you on. Only the age band is kept, never the number.
Pick one of the three paths. Each starts with the two Common creatures and the two weapons shown on its card: Warrior (1) with Bristle and Ember, Mage (2) with Fledgling and Button, Archer (3) with Whelp and Chick. The other classes unlock later in the Classes window.
Type a name (1) - it is yours across the whole tower and on the rankings - then CLAIM NAME (2) to begin the climb.
Your name is claimed and the tower rolls your two starters (1) - their sex is set here and cannot be rerolled. ENTER THE TOWER (2) starts the climb.
Floor 1. Your character stands on the far left; the wild creatures roam the floor (1); the ASCEND portal on the right (2) says how many wins open it. Click a creature to fight it.
A gold arrow (1) points at each new thing the climb opens - the first fight, your weapon, the upgrade, the first egg - with one line saying what to do. It can be switched off or replayed under Settings > Tutorials.
Screenshots are taken from the live game by tools/tutorial_shots.py (dfmc-client) and regenerated after interface changes. The rules behind each screen: system-client-shell, classes.
