Tamer is interesting choice for first playthrough class. As I red the warrior walkthrough guide (which is remarkable help for beginners) you may also want to know that Tamer is quite astonishing from the start.
The other effects can be obtained through Will. However, it requires ranks. Additionally these tamer routines can be combined with increased drop chance via Will. In one evening after defeated boss required for reincarnation I also managed to accomplish all the rares to the top, except silver dragon. I felt I didn’t need it at that point.
You don’t need to invest heavily in tamer routines between all the Dark Rituals, but even some levels may do the big difference.
The tamer-specific combat formation helps you with research drop chance. If you’re into micro-managering you can activate it when a rare enemy spawns. I personally let it auto-run all the way through.
Consider having a lot of flexibility to choose team from different – and able – substitutes!
The good thing is that when you reincarnate, the allies are with you when you start it all over again. This time, however, they can be devastating force and few creatures that lacks still some seeds will get them quickly.
Technically speaking, you can choose different class on 2nd playthrough.
Baby Dragon and Queen Bee help you with drop chance and Sludge helps you with the amount side by side “luck”. Farm Queen Bee first, as she can help you with finding research drops for others. Consider also having Soldier Bee and get excessive Flower-amount to get regenerated honey for level-ups. Rock Turtles do also help on drop chance, but you can bench it if it is required for more easy farming.
You can concentrate on seed-drops more intensively. Bagging in special seeds means you don’t have to wait for hours to complete some tasks that require excessive amount of resources, which only the allies can help to lift the cap with. Tamer most likely saves decently your time.
