"The pyromancer summoned up her mightiest onslaught of fire and rage. Jace feigned interest."A counterspell is a spell that is used in response to an opponent casting their spell, which prevents that spell from doing its thing. Typically, a counterspell has to be specified in the same way that the spell is, so the one casting it has to know the caster and spell that they're trying to counter. In video games with a "casting speed" mechanic, counterspells are typically cast very fast so that they can finish casting while the other guy is still casting theirs. In card games with a last-in, first-out "stack" for responding to opponents, that isn't needed. Subtrope of Anti-Magic. The key distinction between this and Anti-Magic is that this is stopping a spell while it's being cast, rather than removing its effects after it already has been. And keep in mind that simply having the opposite effect of a given spell (e.g. positive vs. negative Status Buff; inflict/heal poison) is not enough to qualify as a counterspell.
- The Fellowship of the Ring. While the Fellowship is in Moria being pursued by orcs (and worse), Gandalf stays behind to hold a door closed. The opposition breaks through anyway. A few moments later Gandalf tells the rest of the Fellowship what happened.
I could think of nothing to do but to try and put a shutting-spell on the door. [snip] Then something came into the chamber [snip] and then it perceived me and my spell.
What it was I cannot guess, but I have never felt such a challenge. The counter-spell was terrible. It nearly broke me. For an instant the door left my control and began to open! I had to speak a word of Command. That proved too great a strain. The door burst in pieces.
- An explicit spell and counterspell appear in Kelson's coronation duel against Charissa in Deryni Rising. Charissa begins:
"Drathon tall,Power come.Conquer all,Senses numb."
- "Drathon kill,Power fade.Senses still,Conquer shade!"
- Harry Potter has these on at least a theoretical basis, most directly seen in Harry Potter and the Philosopher's Stone when a teacher tries to curse Harry off his broom while another tries to counter it. The countercurse was not entirely effective, even though the latter teacher was more skilled than the former, suggesting that counterspells are imperfect as a defense. More common practice is to use shield charms, which block or deflect weak spells, or just use similar spell of equal power so that the two cancel out.
- Dungeons & Dragons
- 2nd Edition, Forgotten Realms setting. The spellstrike spell can negate an opponent's spell as it is being cast.
- 3rd Edition has a Counterspell mechanic. A prepared spell may be cast to nullify another caster's attempt to use the same spell. For example, a fireball can counter another fireball (but not delayed blast fireball, which is a different spell). Some spells are specifically opposed to and counter other spells (haste and slow may counter each other as well as themselves). Finally, dispel magic can be used as a universal counterspell but requires a unique "dispel check" to make the attempt.
- Loads and loads of examples in Magic: The Gathering, including the Trope Namer. Each card in a player's deck is considered a spell, and cards with the types "Interrupt" or "Instant" may be played in response to other spells -- such as those your opponent tries to play. The modern standard for counterspells in Magic is Cancel -- as in, "I cancel your spell."
- Warhammer's dispel dice are an example of this, being used solely to counter enemy spells. There are also various abilities and pieces of wargear that allow instant dispels (the ubiquitous Dispel Scroll), or increase the power of your dispel attempts, either through modifying the result or granting extra dispel dice.
- In Guild Wars, the Mesmer profession has a number of "interrupt" spells that only work on spells and chants, which are given this kind of flavour (as opposed to the interrupt skills available to physical attacker professions, which can usually interrupt actions of all sorts and are given a flavour of hitting you so hard you stop what you're doing).
- The Final Boss of Ōkamiden has its own version of the Celestial Brush and often nullifies your brushstrokes by crossing them out with his own. (Fortunately, this rule works both ways.)
Do We Have This One? I assume not, as there are a number of examples of this sort of thing under Anti-Magic, despite the description specifying something different.
