good spells?

[solemn portal]

I would suggest browsing this forum or asking for more specific things.
The officially best spell is still .
Can't be better than an instant block break.

[fickle remnant]

is a pretty good spell for fire damage

[outer anvil]

What does sensitive do?

[visual skiff]

Avoid setting on fire blocks

[heady bluff]

self and leap is fantastic early on

slow fall or bounce can mitigate fall damage as can a hovering belt

it can be amplified later and even chained with higher mana to point where it’s essentially flight

[outer anvil]

Perhaps you can guide me to make a flight spell ? Tier 2 spellbook is what I have

[forest tundra]

I would recommend what he said, self leap amplifyx3 and I would also add maybe slow falling and or bounce just like he said

I recommend bounce since slow falling is weird and annoying to deal with
