The weaker enemies' HP vary between 20-50. The stronger enemies vary between 50-200. Some enemies also vary by region as well. For example, and Octorok may have 18 HP in Western Hyrule and Death Mountain, but in East Hyrule and Maze Island, they would have 24 and the experience would be 20 vs 30 for respective regions. Dairas' give 100 & 150 experience for Orange and Red. I made similar changes in the palaces as well. Ironknuckles give 70, 100, and 200 for Blue sword throwing ones. No boss gives less than 200 experience. Helmethead gives 200 plus 150 for each head. Carock gives 500. Gooma gives 700, and Barba 1000. Experience bags have no less than 100 with most being either 200 or 500. I wish there was a way to make some 1000.
My experience scale is higher thus the need to give out more experience. I added balance by increasing HP and also increasing Link's attack strength. At Level 8, no enemy except The Great Palace and Bosses take more than 2 hits with a lot of them only requiring 1 hit. I wanted to change the enemies in the Great Palace, but the game goes haywire every time I try to change anything enemy related.
As far as my magic scale, Thunder, Fairy, and Life cost 32 points or 2 bars. All other magic less with Shield, Fire, Jump, and Reflect 8 and Spell 16. I haven't checked the Reflect/Shield combo, but if that works correctly, Then I will make Reflect 16 or 1 bar. BTW, these values are for Magic at Level 8. In a standard game, Thunder is 64, Life is 50, Fairy is 40, Reflect, Shield, Spell, and Fire 16, and Jump is 8 at Magic Level 8.
I also made LIFE spell refill 4 health bars instead of 3.
As far as the Enemy HP, Attack Strength, Magic Point, Enemy Experience,I used Trax's tool for it since I'm still learning hex editing.
I'll probably need a beta tester before I release my hack, so when I'm ready, you can beta test it for me, and you can see my changes.
