The best use of a pet I'd seen was actually on PvP (One of the few times I got it to work), where this player had a Smash+Critical+Lifedrain setup, his pet was a very good defender that would take damage for him and heal both itself and it's player very well. I'm still looking for that defender, but right now my attacker dragon will simply have to do.
Anyway, 5 stars, even though I lost a level 200 character in the great character purge. Restarting was a pain, but what can you do?
Pets don't seem to make any difference in endgame battle, or if they do it's very small. Purple items very -rarely- drop, which I think is appropriate, or would be if you didn't need to go through so many of them to get one that's maxed out. The bonuses are actually (at end game) marginal compared to Epic equipment, which is much easier to come by for nearly any gear setup.
I think it's a slight design flaw, making melee the only way to succeed in this game... then again, it is an Idle game I'm reviewing, but I find it far too much fun to be something that sits in the background! A suggestion if I might, CRITGAME, is expanding our current amount of skills. It would be very nice to see a healing spell of some sort, which would make using a Bow, a two-handed weapon, and spell slinging much more viable in the final levels. Also, the Dragon and Unicorn pets are... somewhat underwhelming, although ??? isn't really a place for pets.
Right now it seems that Battle Without End has just one definitive 'winning' strategy for end-game, which is this:
1. Increase your luck as high as you can. Ridiculously high. Jewelry is best for this. Do nothing but this so you can make +15 gear.
2. Dagger+One handed Melee weapon, raise your Critical and Critical Multiplier as high as you can.
3. Set skills to +Defense +Counterattack +Smash +Lifedrain (The only way to heal in combat)
Smash with high base damage combined with the ludicrous Critical Multiplier of a dagger is sure to get you the damage output actually needed to kill those bosses of ???.
A +14 item is far -far- better than a +13 item, and that's a sight better from a +12 item, but really they both pale in comparison (and sometimes their combined bonuses can't compare) with a +15 item. A +15 Epic Dagger will have 1576 to Crit Multiplier. That's a flat x15 on critical damage. It's wild.

Did you answer "yes" on the confirmation prompt? If you answer no, the reset level stays the same but you get another batch of soulbound items.
