How to play Battle stair

Pick a class and name your hero, then choose the soft trail for lighter foes or the rough trail for bigger rewards and meaner swings. Each fight is turn based: basic attacks chip away at foes, spells spend limited charges, and tonics restore a chunk of HP if you have bottles. When the last foe falls you collect gold and XP, maybe a bonus tonic, then visit the shop to buy gear, refill spells or stock up before you pick the next trail.

Tips

Rough trail scales harder but pays more gold and XP, ride it when you feel tanky
Armor raises max HP and your block stat, so it helps Spark and Attack indirectly by keeping you alive
Watch your spell charges, only some classes learn magic and refills cost gold
You heal a bit each time you level, try to level before you spend tonics
If two foes show up, focus one target before spreading damage around

About Battle stair

Battle stair is an original mini RPG made for quick breaks. The layout borrows the cozy look of pixel remaster-era JRPG battles without copying any trademarked monsters, music or art. Every enemy name is made up, every background is a simple gradient forest from our own drawing code, and there is no scripted story, only stairs, classes and the question of how long your run can last.
