I was actually expecting Tyro's Book too, for a "non-troll" kind of 5*, since it'd fall in that lovely middle-ground of "not ideal, but acceptable." The fact that I got Terra's relic...in one legitimate pull (the 100 Gem pull is a "what the hey, why not")...after I beat my head against the wall on Mog's banner trying to get it...yeah.
Really, the fact that I got a relic for Terra AND Zack, probably my two favorite characters in RK, during the Soul Break celebration is great. Not to mention it's an FF7 Sword and an FF6 Armor, two kinds of synergy that get plenty of use throughout.
Randomly, here's my character relics I have the at the moment and what I think of them! Skipping Zack and Terra's since I pretty much already covered them.
Locke's Rising Sun: Acceptible; I was more pissed when I got it since I didn't have Locke, but that's since past
Thancred's Ninja Chainmail x2: They gave me 2 in one pull...this meant I had 2 5* Armors post Powercreep so can't complain. I like Thancred, so wasn't complaining here
Auron's Shimmering Blade: Hey, a 5* Katana, CYAN AND SEPHIROTH ARE HAPPY! More to the point, yay an Auron relic and a good one (MT Power Breakdown? Huzzah!), I am totally ok with this!
Tidus' Brotherhood: On one hand, I like Tidus...on the otherhand, I can't find realistic use of him. His skillset is uninspired, and I am regretting using a Memory Crystal on him...because he's about to get a reissue and I didn't notice -_-
Lightning's Blazefire Sabre: unlike Tidus, I actually paid attention and didn't waste a memory crystal on her due to reissuing. That said, I like Lightning, and it's a good weapon, so no complaints here.
Tifa's Grand Glove: It's a weapon for Red XIII...that's seriously all it means to me. He's useful as a Support character for FF7 Events and this is an FF7 Synergy Weapon he can use. I like Tifa but I've resigned to the fact that "Monks Suck" and thus won't get use out of her.
Garnet's Storm Staff: I got this well after Garnet hit level 50...it's a high magic staff! I don't mind Garnet, but what this said to me really is "She is your White Mage/Summoner, deal with it!"...
Yuna's Lullaby Rod: ...until I got this. Finally a 5* Rod and a more useful Soul Break, and on a character I like more who can do basically everything the same (And has Support 3 I think), sorry Garnet, you're pretty much pure FF9 now (or if I really need 2 White Mage/Summoners)
Squall's Shear Trigger: It's not the Cutting Trigger...but it's also better than the Revolver...yeah, it'll do.
Rinoa's Rising Sun: ...you mock me game. Giving me a relic to make me consider using Rinoa over other Black Mages becaues "**** you, you will use Rinoa and YOU WILL LIKE IT!" Also it's my 3rd "MT Slow Character Soul Break" AND my 2nd Rising Sun related one...screw you game
Setzer's Darts x2: Ok, one Darts is fine; it's a Soul Break for Setzer, and clears up some synergy concerns for like Locke and such during FF6 Events (both characters like the Rising Sun.) Unlike the Ninja Chainmail, a 2nd one of these feels completely pointless and seriously, **** you game for giving me two of the one relic I can't really make use of! I mean, heck, 2 of Rinoa's Rising Suns at least would feel meaningful in case I found a reason to use Hope AND Rinoa at the same time (and eventually Edea down the line) but this is just trollolololol
Balthier's Ras Alghetti: From the Dr. Mog give away, it's a 5* Gun, something I don't have, so the choice was obvious here. I don't care about Balthier much, more the 5* Gun, since now characters like Sazh and Barret (AND IRVINE!!!!) have legitimate weapons (that aren't Knives), as well as Lightning and Balthier now being able to do their "ranged Spellblade" gimmick appropriately.
Tyro's Sentinel Grimoire: Randomly did a 900 Gem Pull, got this, I am not allowed to complain because it's the freaking Sentinel Grimoire
