I think it really depends on what you need and what other heroes you have.
For the information available @Glenn’s answer makes a lot of sense cause both Sartana and Rigard are very versatile.
I don’t have Sartana yet, but i think that leaving here at 2-60 is a bit of a waste, while she’s probably already much usable at 3-70.
However, if you have no rammers but already 1 or 2 healers your titan hits could get a boost from Tiburtus rather than Rigard.
Ok, I would Rigard or Tiburtus depending on your priorities (I would raise Sartana in any case):
if you value more events/titans I suggest rising only Melendor as healer (more squishy than Rigard, but dispel enemies is very useful while dispelling allies can be done easily with small green pots, or counter banners, e.g. turtle banner against defense debuff), and going for gormek and tiburtus as rammers;
if you value more AW then maybe 2 healers (Melendor and Rigard) are better than 1.
Probably going for option 1) will make you grow faster, cause events and titans provide ascension materials more rialiably than AW, and if you learn to play raids in an offensive way 2 rammers will work pretty well for AW too
Actually I think tiburtus is the best choice since I prefer titans/campaign/events. Then u suggest to go for 3/70 sartana instead of Gafar/merlin/proteus etc?
The “problem” is that I have kiril/melendor as healers but no good purple attacking hero. Maybe at this point it is better to go for tiburtus (for events) and raise sartana.
Seems everyone agrees on doing Sartana. For what Tiburtus and Rigard are concerned they are both very good heroes and it depends on your taste I think (I would do them both in any case in the longer period).
In the past I did Rigard first myself and used him everywhere, but with the benefit of hindsight I would have invested less in healers and more in rammers to start dealing serious damage to titans early in the game.
Depends on when you think you’ll score that 5th and 6th tabards. You may get 8 more tools by then anyways. Morlovia is your only guaranteed source and that was recent. So you’re at least months away from two guaranteed tabards. Sure you may be able to buy one for $10 at some point, but really, I’d save the $10.
If it were me, I’d do Merlin & Rigard. Rigard is my favorite healer period and Merlin is a game changer on raids and events and can be really helpful on titans as well. Tibs is great, but his skill is duplicated by two other 4* and a 5*.
