Damn, i'm runnin' out of sq and that gramp not answer my summon call. My sq is 30. Is anyone have a summon trick or ritual to get Hassan?
Kill someone. Doesn't matter who.
Death is the catalysator to summon him.
Jokes aside, it's the same as with all other summonings.
When I was rolling for him, I tried a few single pulls at first and got some rather good CEs like Black Grail.
So I thought my luck is on a high level at the moment and did a 10-Pull in which he answered my summonings.
Maybe you can try that as well.
There's one surefire trick to getting him; you whale, and whale hard. Otherwise, there's really no helping things. You're just out of luck if you don't get him. My advice? Just look at the list of Servants and their release order and start saving up and planning ahead for the next 2 years. Some Servants are more likely to come out more for random banners, so prioritize the rarer ones. I'm personally not going to spend any SQ until the Sakura clones are out. That and this year's Summer Servants are my main targets for this year.
I guess it's easier to wait when you've got a reliable stable of Servants and friend supports. I know I was rather impatient on these random banners since I sorely needed stronger Servants I could rely on to be the core of my team, and I finally managed to settle on a reliable collection of them at last. Now I'm just going to be raising the ones I neglected (like Jeanne) until the banners for the Servants I want to get arrive.
He's pretty cool, but not exactly essential. You're better off planning your spending than hoping you get lucky with your last roll. Granted, I managed to roll for Illya with my last 30 SQ at the 11th hour in the Prisma Codes Event, so who knows?
In the end, it's just one last 10-roll. If you think your spending habits can take the hit from that, and you're willing to shoulder the possibility of disappointment, then go for it. You really might get lucky.
Was in the same situation, rolled in despair, and the last card turned out to be him. Have hope, and good luck!
And worry not if you don't get Gramps, Jack the Ripper is his contender as the best Assassin in the game, and she gets many rate-ups this year (the first one being in April). There should be another King Hassan summoning campaign in November this year, so if you want him so badly, you can try again then. Just make sure to plan ahead of time which servants you want the most this year in order to have a good amount of SQs for Gramps.
Maybe try to have all 3 Hassan of the old man mountain servants present in your party?
When I summon him I had Cursed Arm, Serenity, and Hundred Persona in chaldea and each of their NP was above lv 2. Since he came in my first summon it was as if Cursed Arm, Serenity, and Hundred Persona played a role in summoning him to complete the current Hassan Family.
Maybe First Hassan will answer your summon by establishing all 3 Old man Mountains.
