As all my wizzy friends said most of farm places for HW is concern on rare drop, hunt for card is easy for even mage without huge INT ot IC (it's my way of gearing up) - Creamy, Vitata, Stem Worms is easy, have good prices and always wanted. But there is one hint about heavy loot and owerweight - hw don't really need GEC for SP (for solo farming GEC is more usable for heal over time) cus you have Soul Drain (also passively boost your SP) and trick in using single-target spells for replenish your SP between AoE spells usage (some idiots try to gather huge pack of mobs thinking like "huge pack = more income" and reel all over the map for every single mobs without killing already huge pack but forget about "more time no killing = less income" so as about Server Rules - "Mobbing a lot of monsters on the map is only allowed if it does not affect the other players on the map."). So HW can hunt even for not rare drop but weight is always be your strongest enemy. If we thinking about 200m budget it will be something like that:
Moonlight is sweet for begining, DTS is good and you can enchant it for more INT (look at mATK table topic), never take equip with DEX chanted if you planning to gear up your HW (only if you like resell items and lose zeny or time on it, after you get your SoM with bonuses you already need to sell your items with DEX cards).
