1. Have all helpful items
- Cereal (Temmie Flakes) Heals for 10 Stamina after a certain point in dialouge for showing it off.
- Glass of Water (You can only hold one unfortunately), Heals for 20 or 25 Stamina
- Carrot (Almost forgot to mention this but the rabbit lady is awful to dodge), use this on the rabbit lady immediately to skip her fight after dodging one attack.
2. Cheat
- Yeah, the reaction speed needed for dodging is bit unnatural in this game. So why not cheat with the tools you're given for now? You can kind of spam pause the game during the fight to slow down the game to be able to react to attacks a bit better and not die.
- You can also lose the fight twice and after get the option to sell your soul to Chara for a 25% damage reduction. You can get the reduction by going to ITEMS in battle and selecting Chara's promise (As far as I know, there are no downsides besides pride and a screen change during the fights.)
3. Patterns
- After losing to this fight a bit too many times (some Voluntary), it's important to remember the attack patterns of enemies obviously. But for this fight, save your healing items until you've already picked the Temmie Flakes and NO option for not having eaten her doNuts. After that, heal asap according to your Stamina if you take damage. I've seen a lot of people play games where they heal when they are on death's door (Don't do this). This is because you'll get a decent heals during the fight. During the last phase of the fight with the ACT fully unlocked, don't use healing items. You'll have plently of healing provided when dodging (don't risk it if you are low on Stamina) .
