1. Bow has great atp as well as ata so it can be used to kill other things with hard attack. water gun is another option (I prefer the water gun bullets for hell anyway they seem to be more successful)
2. These are great in tower quests or against mini bosses such as girta, baranz (whilst shocked/frozen or they'll nuke you faster), gibbles, meri, epsi, gi gue etc.. and groups of delbiters, del lillys (2 activations on a fleshie and they'll self destruct. If you let the lilly lean forward to take aim you can hit it twice) or groups of anything really. You can use these to lower enemy hp then use dark meteor to finish them off. If you don't own a dark meteor and you are ramar/marl or you are too weak to do much dps in ultimate, you'd most definitely want to carry these everywhere.
