I ended up trying every character in Caladrius. Some quick notes.
- Using the element shots early and often is the key to both survival and scoring. Survival because dealing damage with them builds up your ether gauge (bottom left) to earn chips that let you upgrade (and even re-spec) elemental shots between levels. Scoring because killing enemies with them builds your multiplier. The regular shot has neither of these benefits.
- Some element shots fire your regular shot at the same time. This lets you deal extra damage, but tends to negate the two above benefits of using element shots. Remember which part of the shot is which.
- Don't forget that every character's defensive element shot cancels bullets in some form or other. Some of them are very hard to use, but others are almost foolproof.
- Destroying certain enemies and boss parts makes orange fragments drop. Fill up the middle gauge with nine of these to get a 1up.
- Beat the game with at least two characters to unlock custom element shot loadouts (but to open it up fully you will need to beat the game with every character). Now you get to try to break the game to your heart's content.
- Don't forget to try synchro mode, which lets you play a two-player game where 2P is mirrored and also invulnerable. It's hilariously unbalanced, and also lets you see all the unique dialogue between all two-character combinations (solving what I call the Castle Shikigami problem).
Character choices:
- Maria and Noah are good for beginners due to very effective crowd-clearing attacks. Maria has a powerful frontal shot, but Noah can instantly wipe out whole mobs with a very fast homing laser.
- Alex and Lyris have more power while still having good range, but you need to get up closer to use their most powerful attacks. Lyris has a directional regular shot that's very flexible but basically destroys scoring potential.
- Kei and Sophia are more technical, growth characters that require you to be carefully positioned and max out upgrades to realize their full potential. Kei feels very hard to use because his gauge drains fast. Sophia's gauge drains slowly and has a defensive shot that makes you nearly invincible for basically free.
- Caladrius and Lilith are high-power characters who drain gauge very quickly, with weird shot patterns that are hard to use.
Thanks for this. Despite owning every version of this game, I haven't played any of them long enough to pick up on those nuances. Your first point about element shot especially explains my lack of progress in the game. I've trained myself over the years to never use the bomb/special attack, only the peashooter. So I see how a game built around the special shots is beyond me. I guess it's time to start using that B button.
