My first five bond CE :

1. Jack the Ripper (stuck at bond level 10)

2. Jeanne Alter (stuck at bond level 10)

3. Xuanzang Sanzang (on the way to bond 11)

4. Arash (on the way to bond 13)

5. Georgios (stuck at bond 10).

I find at least for Lancelot or jack that given how they’ve basically carried me through the game to a degree leveling their bond was a tad easier. Even if i wanted to try out other characters i kept htem in my teams roster at the back just in case.

Good for you. I don't use them anymore since I already get a better servants. But still, it was great time, I think it's the first 3—4 months I play.

1. Herc

2. Proto Arthur

3. MHX

4. Hans

5. Arash

Got Herc, Proto Arthur, and MHX first week I started playing the game and used them till LB1 where I bond 10 them. Twas rough mainly using a niche saber and an unbuffed MHX (Since they were my only SSRs for the longest time). Camelot was especially rough.

1. Altera (bond 12 now, and keep going up)

2. Quetzalcoalt (bond 10 to 11)

3. Minamoto no Raikou (bond 10 to 11)

4. Tamamo no Mae (Lancer) (bond 10)

5. Arash (bond 10 to 11)

I really hope that they add more bond level, like bond 20 at least

Okey, here we go:

1. FIrst Hassan (bond 10)

2. Merlin (on the road to bond 11)

3. David (bond 10)

Also I'm a bit jealous that you have bond 12 Lancelot, but... well I despite he is my favorite character I got him not so long ago, so that's the case.

Skadi in December 2018 (now Bond 15)

Edmond in January 2019 (after being stuck at B11 for two years he's about to hit B12)

Enkidu, BB summer and Gilgamesh archer in May 2019

1) Hans

2) Waver

3) Merlin

4) Kojiro

5) Hokusai

Basically, most of the servants I got early game. Though I gave Merlin and Hoku bond grails and might give Hans one someday.
