Do you have any advice, tips, tricks, since I am starting over? I intend to play fairly casually, as in I won't be trying to max a build or see all endings, etc.
1. Morale controls how enemies scale relative to you so raise it by planting flags and run away if an enemy is too tough.
2. If you want to buff your damage and spam Martial Arts invest in Fire Phase.
3. If you want to debuff an enemy or spam wizardry invest in Metal Phase.
4. If you want to be an equipment towing tank with huge close-range damage or use deflects to force enemies into submission invest in Earth Phase.
5. If you want to ease up mechanical restrictions on your abilities and have mid-range versatility invest in Wood Phase.
6. Do not invest in Water Phase until you get to the Sage that can reset your attributes as it is best suited for long-ranged spam with heavy investment (and stealth).
7. Weapons in the first playthrough are only as good as their Martial Arts which are permanent.
8. Salvage low level armor and weapons you don't need to get gems as they are often worth more. This can be automated in settings but be sure to lock what you covet.
9. If a boss is too tough you can often flip the script by changing to a different element with the Sage's help or more conveniently with battle sets you saved.
10. Do not do side missions (except Training Ground ones) unless you want to level up or farm for gear as they will wear you out otherwise.
11. The divine beast Qinglong summon found early in the game is ideal for healing allies and self when Dragon's Cure is limited.
12. Best way to approach enemies is to take out (or aggro) the farthest ones out with a ranged weapon systematically.
13. Use up Genuine Qi before facing an area boss as they will more often than not prevail over you and require several attempts where retrieval is a handicap.
14. Once you beat the main game you will open up whole new equipment categories and weapon upgrades and raise upgrade level limitations.
P.S. It is kind of obvious but the five elements have a rock, paper, scissors interaction based on diagram. [Water>Fire; Fire>Metal(Poison); Earth>Water; Wood>Earth; Metal>Wood]
