Title: Landstrander
Location: Earthborn Seal
Boss: siglint
How to earn: Down siglint 15 times using hemdrills to bring it down.
Required item: small bomb
How to farm it: Run the battle with low level or no armor on normal mode. Bring small bombs with you so you can bring 14 bombs at a time per battle. Dodge siglint's attacks until he prepares to go for an instant kill, which will prompt the player to use bombs to target the hemdrill mounds. Timing is key for this part. It can be soloable, so be careful not to waste bombs. In the event you run out of bombs, you can always reset and try again. If you bring a party, then the crashed siglint will count towards the one who crashed it down.
Title: Brainfreezer
Location: Earthborn Seal
Boss: Beokros
How to earn: attack beokros' head with his ice fragments 15 times.
Required skill: anything that can knock him down without destroying the ice in the process. This includes ultimate skills.
Recommended classes for holding: Evie, Hurk, Karok.
How to farm it: This one is more of over time and hoping you have a buddy to tag along and help you. Have your friend pop an SP increase potion if they have one right as the battle starts, and wait for beokros to do his blizzard attack that envelops one half of the map. Once beokros lands and you have the ice in hand, have your buddy use their ultimate attack, and position yourself towards beokros's head with the ice spear. Wait till the ultimate skill finishes, where you have exactly half a second to react before beokros gets back up. If timed right, you will get a bonus mission stating you attack his head with the ice spear. Be aware that the recommended classes have varied timings, and Evie has two holds at her disposal. Repeat this process as long as you have SP potions to spare. If you run out, you can always wait until you get the craft with expertise daily where you can craft a 10 second item to get 2 more SP pots every time it pops up. This will only count for the one who attacked it, so if your friend wants the title as well, you have to switch positions and repeat this process until you get it. Timing is also difficult as well, so it's okay if you don't get it on the first try. If you feel that you are wasting gold, you can always take a break on this and try it again when you have more. Additionally, any class that has holds can also work, but the ones recommended have short ultimates, and can be timed efficiently. Another way is to keep attacking until he gets knocked down, but that's more of chance and can kill beokros when you least expect it, locking you until the next day. Ice fragments can be gathered from Beokros's ice prison, and the ice pillars that cover the middle of the map.
EDITS: Corrected the quantity requirements as mentioned.
