Heres what [i think] the weapons do at level 1, the effect/duration gets stronger the higher level item,
zeal:speed 2 for about 8 secs 120 sec cooldown
ethereal: you get a very heavy slow [about same as warming up skills] for 4 seconds then after that get a HUGE speed boost for 8 seconds. 120 sec cooldown
emberstone: gives yourself fire res for about 8 seconds... 120 sec cooldown
duskbane: gives yourself healthboost for [an unlimited time???] [??? secs cooldown] [the health boost isvery bad its like 8hp so this is kind of useless]
prismatic: gives yourself and others near you speed night vision and water breathing , not sure about duration/cooldown
hellforged: withers yourself [deals about 10 damage total when wither finishes so barely any] and gives you ressistance for about 8 seconds
dark pearl : blinds yourself and poeple around you
blessed: gives yourself and poeple near you slowness and a regeneration effect [very weak healing tho heal is about 30 secs]
deeproot: slows yourself and poeple near you
stardust: gives yourself jumpboost and a minor speed boost [my personal favorite ]
luminous: dunno what this does...
Heres what the armor does... btw this could be wrong its been a while since i used all of the items,
zeal is a minor health buff and focuses on protection enchants
ethereal is a big health and knockback ressistance down but a big speed up and almost no protection enchants <--- my personal favorite lol
luminous same as ethereal but less speed less health lost and no knockabck ressist lost and a bit more protection enchants
stardust is a minor speed buff and some protection enchants
hellforged reduces health by a good bit gives a minor speed buff and then focuses allot on protection enchants
emberstone is... a minor speed and health buff and then... fire protection [wow much usefull]
deep root is a [the biggest?] health buff and [the highest?] protection enchants. but ahuge speed reducion
blessed is a high amount of health knockback ressistance and some good protection enchants
dark pearl is minor speed minor-medium health and minor-medium Knockback ressist, but none-very little protection enchants
dusk bane is litteraly just lots of vanilla minceraft enchcantments and no special attributes at all
prismatic is a very minor speed buff [and possibly health] and then focuses on lots of enchants
Again. im not 100% sure on this XD
