Ultros ( Final Fantasy XIII - 2 ) Ultros is a downloadable content monster along with Typhon in " Final Fantasy XIII - 2 " in the match , " Uninvited Invertebrate " . Battle . During the first battle phase , Ultros uses Octopus Ink for low damage and Slow and Curse . His basic attack hits for low damage , and his most powerful attack , Frost Breath , is spread across a wide angle . Ultros is susceptible to Poison and other debuffs . When he hits half HP , he will summon Typhon through a cutscene , and will be at full health . After summoning Typhon , Ultros becomes full bent on supporting his powerful friend and will use buffs like Bravery , Faith , Protect , Shell , Veil and Vigilance on him . Ultros is virtually immortal at this point , and if he ' s even close to dying , Typhon will restore him to full HP , meaning Ultros cannot be felled unless Typhon dies first . Typhon will most likely remain buffed for much the fight and his attacks are lethal . Ultros will use his own attacks , which , if properly combined with Typhon ' s offensive , can put the party in a severe situation . When Typhon uses Snort , he will be rendered defenseless with multiple debuffs and Ultros will dedicate himself to removing each debuff and healing Typhon for 10 , 000 points for each debuff removed . When Typhon is defeated , Ultros attempts to run away , but Serah and Noel combine their attacks to fry Ultros by means of Cinematic Action . Achieving the " Perfect " score from the Cinematic Action bestows Ultros ' s summon crystal to the player . Strategy . In the first battle , it is recommended to damage Ultros by means of Relentless Assault and Cerberus paradigm s . Ultros is for the most part an easy opponent , as his attacks during the first phase are not life threatening . If the party is far from Ultros his Frost Breath attack does small damage , but can hit multiple times if the position allows him to do so . If the player is level ed enough they can easily cripple Ultros ' s HP down via Poison . When the second phase starts , Ultros becomes dangerous , not because his powers increase , but because he becomes the biggest annoyance . The player must focus on Typhon , and since Typhon will be buffed for most of the fight , the player should do the same , as well as attack and heal constantly . Paradigm Pack . Ultros is a Synergist , and like many other Coliseum monsters , has six ATB gauge segments and his level caps at 13 . While his stats are impressive , his skillset is not , for he only learns Protect , Shell and Endless Blessings . The player would need to make many infusions for Ultros to get more abilities ; this can be an advantage , as the player can customize him to their liking . Ultros ' s magic stat can potentially exceed 1 , 000 , making his Feral Link powerful : Octopus Ink , causes Magic - based damage and attempts to apply Curse , Pain , and Slow — a status ailment unavailable as a spell — on a group of foes . He has has Feral Surge but not Feral Fatigue , meaning the moment his Feral Link gauge fills he is bestowed with Bravery , Faith , Vigilance , Veil , Protect , Shell , and Haste . Ultros is a relatively slow caster and sometimes suffers from repositioning issues , slowing him down further . However , the player is free to customize his skillset . One build is to give him all the defense - oriented buffs , as he is the only monster to have Defense Maintenance II , a passive ability that lengthens defensive buff duration . The player can also guarantee Bravega and Faithga if those are the only other spells one teaches him , or guarantee that he casts the longer - lasting single - target versions if one teaches him only those . Other appearances . " Triple Triad " . Ultros and Typhon from " Final Fantasy XIII - 2 " appear on Triple Triad cards in the version playable via " Final Fantasy Portal App " . Etymology .
