Huntera's whole spell book, priced as Huntera prices it: mana and
cooldown are the capture's own numbers and are not Tibia's — attack
spells cost half of what they cost there, and utito tempo costs 290
against Tibia's 20. Where a row names the tibia.dev spell it mirrors,
tibia links the two so a client can fetch a sprite; nothing quantified
crosses over.

Both numbers take a bound: filter[min_mana] and filter[max_mana] over
a capture spanning 6 to 550, and filter[min_cooldown_ms] and
filter[max_cooldown_ms] over one spanning 1,000 to 40,000. The bounds
are named _ms because the column and the payload key are — a bound
named for the bare word would read as seconds.

Every spell also carries the seven fields the game publishes about the cast
itself. area_tiles is the squares it reaches as [dx, dy] offsets from
the caster, 1 to 88 of them, and target_tile is the single square it is
aimed at where it names one — always one of that spell's own area_tiles.
The other five are for a renderer: effect_color, missile_id,
effect_id, effect_step_delay_ms and directional. Read directional
carefully, because it has three states and only two of them are words: the
game publishes true on 31 of the 57 spells and nothing on the other 26,
and it publishes false on none — so null means the game did not say, not
that the cast ignores which way the character faces. None of the seven takes
a filter today for that reason and for the JSON columns' own: a
filter[directional]=false would answer none of the 26 a client means by it.
