Caladbolg



Caladbolg is a recurring weapon in the Final Fantasy series. The Caladbolg is generally the ultimate weapon for Tidus, however in the original Japanese versions the weapon is called Ultima Weapon.

Final Fantasy X
The Caladbolg is Tidus' Celestial Weapon. It is acquired after beating the chocobo trainer in the Calm Lands, down a slope in the northwest section. It requires the Sun Crest and Sun Sigil to power it up to full, and when powered up it gains the abilities Break Damage Limit, Triple Overdrive, Evade & Counter, and Magic Counter, in addition to dealing more damage the closer to Max HP Tidus is.

Dissidia Final Fantasy
The Caladbolg is Tidus' weapon when in EX Mode and has two EX Mode abilities related to it: "Caladbolg (ATK)" and "Caladbolg (DODGE)". The Caladbolg abilities boost the Bravery damage Tidus does depending on how much HP he has in relation to his max HP, doubling his Attack at full HP, and doubles the duration of invincibility during his dodges.

Dissidia 012 Final Fantasy
The Caladbolg returns as Tidus' EX Mode weapon with no new abilities, and unchanged effects of the ones introduced in the original Dissidia.

Etymology
("hard cleft"), sometimes written Caladcholg ("hard blade"), is the sword of Fergus mac Róich from the Ulster Cycle of Irish mythology.
