Hello! First of all, congratulations on finishing this version! Also, thank you so much for reporting the Red Dragon battle bug. As a token of my appreciation, I'll add your name to the credits in the next game update!
Well, in the current version, it's practically IMPOSSIBLE to defeat Sheol, the archlich, but one possible strategy is:
- Spend all the money you've earned throughout your journey on light damage scrolls and expensive healing items.
- Equip the Ring of Hope, which reduces the heavy dark damage Sheol deals by 50%.
- It's important to learn his different combat patterns through trial and error. Also, at one specific point in the fight, you need to know exactly when to defend. If any character takes that attack head-on, it's an instant kill (even while wearing the Ring of Hope).
- Be lucky during a few turns (I know, that's unfair lol).
Finally, I don't know if this will motivate you, but Sheol is one of the bosses that drops one of the two legendary items available in Part I of the game. On top of that, he rewards the player with an absurd amount of money.
However, if you'd rather take on a challenge that's a little less insane, I recommend waiting for the next game update. Ariela will obtain the final blade she needs to become a complete warrior. With this new technique, your chances of defeating Sheol will be considerably higher. Furthermore, it's not 100% confirmed yet, but there might be a third party member who can help you in the battle against Sheol.
Unfortunately, the Desert Tower will only become accessible in Part II of the game.
