Gram

Unlock
Wolf of Nobina is a special boss that replaces the newbie ground boss if your party items includes a single runestone. It is tougher than a D3-10 boss. Defeating it for the first time awards you with Gram which is a unique named Tier 4 weapon which also starts out as SSS+20 (20). Defeating it multiple times provides no additional rewards.

Upgrading
Currently you cannot upgrade Gram, however with future Patreon Bosses added into the game, your Gram will be upgraded each new Patreon Boss you defeat.

Wolf of Nobina
You can fight this battle if you take 1 Runestone with you to the Newbie Ground and fight 6 rooms. TBA Winning this fight will give you Gram.

Fawn / Wisps
You can fight this battle if you take 2 Runestones and only 5 party members with you to the Newbie Ground and fight 6 rooms after Wolf of Nobina is defeated.

The goal in this fight is to heal Fawn to 4 million hp. The percent based heal power of your supporters is diabled in this fight. The Wisps do a lot of damage so your whole front row needs very good defense and because the percent based heal power is disabled, water gems on your equip are not very useful. The back row supporters should go for full attack and hope they don't get attacked often.

A good team in this battle would be 2 defenders and 3 supporters. Neutral pets are at an advantage and hourglass helps to keep your supporters on 3 actions because the enemies will slow your pets down, potentially halfing your speed. Both defenders want to have at least 4000 defense with all elements positive and hourglass on the front row wants to have more than 1000 defense with all elements positive. All pets should be higher than level 200/55 with 150k+ growth or you will surely lose.

Best team composition Front row: Dog, Anything (defender, maxed titanium equip with earth gems), Hourglass (Supporter, Titanium Armor with earth gem, Inferno Sword + Inferno Gloves with fire gem) Back row: Any supporter specialists (supporter, one supporter Gram with fire gem, all other equip inferno with fire gem)

Winning this fight will upgrade Gram to SSS +22 (22). This will increase the attack to 79, all elements to 90 and the extra exp gained to 22%.
