Cozy fire orb has a +10 bth boost flat, not lean, only applied to fire spells
Cozy Fire Orb boost ALL of your attacks (melee/ranged/magic/spells/skills/etc) by 10 BtH and DOES NOT affect pets/guests.
Just to clarify this. Cozy Fire Orb is an older version of Greater Water Orb in terms of balance, eventually Cozy Fire Orb will be updated to match Greater Water Orb. However at the moment the two are completely different.
Greater water orb has a +10 bth LEAN, only applied to water spells
Greater Water Orb is basically a nerfed version of Cozy Fire Orb, specifically affecting spells as Andlu stated. Additionally for clarification, the +10 BtH lean on Greater Water Orb DOES apply to all attacks HOWEVER after calculations it ends up only affecting the BtH added to spells (when compared to Cozy Fire Orb).
Summery for Cozy Fire Orb and Greater Water Orb:
The only difference between these items (at least at lv 150) is the BtH given to spells. Cozy Fire Orb gives more and Greater Water Orb gives less (change made due to balance, as stated above Cozy Fire Orb will get an update to match Greater Water Orb eventually).
Osiris has +10 bth flat boost, and gives +5 BTH to any spell, not only light
Since spells get +5 BtH then magic attacks should get +13.333... BtH
Goggernaut helmet just gives +10 bth to you, your pet, your guest and the monster. Also gives +5 BTH to spells(if balance is right, not certain about this as well since info subs makes it sound like spells get +10 bth)
I'm fairly certain that this is just a flat +10 BtH to everything, the most probable balance reason for this existing is that if all monster attacks (normal, SP skills, MP spells) get +10 BtH, so do all of the player's attacks (Normal Attacks, SP skills, MP spells, SP spells, Pets and Guests).
