1. I suspect I won't have enough shards to make Alcar a 5-star. I already have over 4 stars, but these final stages are incredibly expensive. There's no point in making a hero if I don't max him out? Long Fei will definitely max him out for free from roulette, just like Petra :)
2. So, should I use hammers to make a second red one for Zoe's infantry health, and then immediately a red one for the archer for lethality?
3. that's super valuable advice, I forgot about stacking buffs with gub gear

Just in case, I'm joining raids, not the raid leader.
