Fate/Grand Order NA. Camelot.
Chapter 12, Arrow 4. Tristan fight.
Clearing this fight relying on support saber is pretty easy.
As you can see, support Lancelot not even max lvled.
You need decently leveled Leonidas (higher lvl - longer h will tank), Hans and Mashu.
Take support Lancelot / Rama / Okita /Nero (Bride) and you are fine.
Hope this may help new players.
Thanks for watching!
