The fight against Lichdragon Fortissax involves lightning that lingers on the player and does delayed damage, so it forces you to be constantly moving around. This means you lose out on attack opportunities when trying to fight him in melee range because you have to avoid attacking when the lightning is tracking you. I didn't like having to wait for attacks like that so I tried using magic and oh boy, that is so much easier. When you're not directly next to him, he has a habit of just slowly walking towards you so you have tons of time to attack at medium range.
My strategy was to frostbite him right away and then again after a critical hit, and to use rock sling to try to stagger him when he is frostbitten. I was doing surprisingly high damage for having non-upgraded weapons, it really wasn't too difficult. When he finished his long slow walk towards me, I just tried to run under him to make some more distance as running away from his head didn't work very well.
The loadout I used in this video:
- Meteorite Staff (picked up off the ground in the Street of Sages ruins in Caelid's swamp of Aeonia)
- Rock Sling (found in the basement of the Street of Sages ruins in Caelid's swamp of Aeonia)
- Misericorde with Chilling Mist (weapon is found behind a stonesword key fog wall in Stormveil Castle, and the ash of war is dropped by a teardrop scarab in the ruins south of Renna's Rise in Liurnia after progressing past Caria Manor)
- Radagon's Soreseal (found in Fort Faroth in Caelid behind a giant rat)
- Marika's Scarseal (found by teleporting to a secret area of the Siofra River region under a waterfall, doesn't require any fighting to pick up)
- Stargazer Heirloom (found on top of the Divine Tower in Liurnia after using the Carian Inverted Statue at the Carian Study Hall)
- Ritual Sword Talisman (found in Lux Ruins in the Altus Plateau region after defeating the boss)
- Lantern (purchased from a nomadic merchant on the west coast of the Weeping Peninsula by the Isolated Merchant's Shack site of grace)
In the thumbnail, RL1 means "rune level 1", WL0 means "weapon level 0" or no weapon upgrades, and "hitless" means I didn't get hit :)
