it's basically the item farming version of re:start but a copy&paste of renewal with level cap, you have to complete quests for base levels and they also grant you buff potions. fever field (dynamic field i believe not sure why they are using a different name) drops mythril ores that is used to craft costume wings and perhaps other costumes as well. you must first make it into a mythril by crafting condensed elunium (enriched elunium) with elunium and zeny. so if a wing requires 75 mythrils it's likely 750 ores and 75 elunium.
here are the three cash shop premium packages, they last 1 month when use the box.
account package - increases experience, and drop rate by 30% reduces death penalty by 50% doubles storage capacity for all characters on your account.
essential package - 70 dollars worth of teleport and buff service for an affordable price! it gives 20% experience / drop rate as a bonus. (it's what it says) provides Morning Dew of Yggdrasil that is required to teleport to a map or use the buff service (blessing of yggdrasil: all stat +7 Atk +30 MATK +30 HIT +5 FLEE +5 (1 dew per teleport or service, it does not include the buff duration.)
hunting package - provides 50% experience and 100% drop rate that lasts 1 hour, twice a day for free! (that's what it says lol)
remote shop that allows you to buy/sell at any place and remote storage feature that allows you to deposit / withdraw at any place is included.
they could have just said bubblegum x2 battle manual x2 (which they did but after a wall of text) ¯\_(ツ)_/¯
[additional service] uses jelstar as the cost and provides the following service - bubblegum or battle manual for 1 hour (2 jelstars) and bubblegum or battle manual for 24 hours (25 jelstars) this package might be the only way to recieve bonus exp/drop rate.
