Selective Spell Shield

[Wrda]

So it's completely limited to instant spells, or missile speed 0, hm. I guess that's an interesting find.
I would put the static method Filters before onPeriod, just for user convinience.
The name 'onPeriod' implies the timer being periodic, which isn't the case, I would rather rename that.

This looks decent. The code could use some tidying but it appears to work as expected. Here is some wurst code for a similar effect:

package SpellShieldWithCustom
import Abilities
import DamageEvent
import SoundUtils
import Castles

constant SHIELD_SOUND = new SoundDefinition(Sounds.spellShieldImpact1)

init
    DamageEvent.addListener(0) ->
        let target = DamageEvent.getTarget()
        let event_t = DamageEvent.getType()
        let damage = DamageEvent.getAmount()
        // To selectively spell shield, set the cooldown here to 999
        // Then use nullTimer() -> closure to unset it as desired
        if (
            target.getAbilityLevel(ID_EXASPERATION_SPELL_SHIELD) > 0
            and event_t != DamageType.ATTACK
            and target.getAbilityCooldownRemaining(ID_EXASPERATION_SPELL_SHIELD) <= 0.
            and damage > 0.
            // Your custom conditions here
        )
            DamageEvent.setAmount(0.)
            SHIELD_SOUND.playOnPoint(target.getPos3Real()).snd.setVolume(127)
            flashEffect(Abilities.spellShieldCaster, target.getPos())
            target.setAbilityCooldown(ID_EXASPERATION_SPELL_SHIELD, 1, EXASPERATION_SPELL_SHIELD_COOLDOWN)
