Ok Niliu Im glad to hear you are starting to dominate buddy. Your animal and thrall strategies are sound at this point. And your Attribute loadout is solid for a player at your level. A couple of things regarding pets and thralls which you may or may not know, but come in handy. If you feed them their preferred food (pictured in their inventories) after breaking/taming, they will gain a 25% damage bonus when attacking. This wont be obvious to look at until they are in actual combat, when you will notice they have a small ‘fist’ icon above their health. Now regarding healing. If you are a kind master would like to heal your thralls, you can do so by shooting them with Healing Arrows. These are unlocked via Specialist Ammunition II in the feats, BUT not until level 38 unfortunately. Furthermore, for some strange reason they dont appear to work on pets (Funcom if you are reading please consider changing this). Both of these are purely optional, just though I would let you know.
Now regarding that Thick Hide you seek! There are a few possibilities to obtain this, which I will go over. Two of which will involve mounting an expedition into new areas which I think you should be able to manage, the other (untested) could work from home. Some of the most common enemies which drop Thick Hide are: Gorillas, Elk Kings, Rhinos, Bears and Elephants. I recommend targeting either the first or third. Locations:
1) Gorillas: head east and into the Jungle biome friend. They are scattered throughout most of the Jungle. But especially around coordinates N,5 and N,6 The Lost City of Xel-Ha. There are 2 types, a Grey Ape who is fairly close to the same size as a man, and the larger black Gorillas. Only the larger black ones give Thick Hide. Because of their size they look imposing, but as with all primates in the game, they are actually really slow moving and easy to dodge. In fact almost all of the creatures in the Jungle are fairly manageable, so when you decide to test your metal against another biome, the Jungle is the best place to start.
2) Rhinos: head north-west to Sepermeru the human city. If you spoke to Arcoss the Wanderer near The Sentinels, you may remember he mentioned this city, time to have a look see. It is basically to the left of the Unnamed City biome (large redrish orange patch on the map) starting at coordinates B,6 on the map and stretching further northward. Easier route is to head west past the bottom of the Unnamed City THEN north (not vice versa). There are always Rhinos on the plain outside the city. They do move faster than Gorillas and hit harder, but drop more Thick Hide. Their main attck to watch for is a charge after pawing the ground (dodge then back/side blows). Also whenever you do go here you can look around Sepermeru. It is a treasure trove of resources early on. Almost 90% of its inhabitants will not attack you unless you instigate violence. There are a few pockets of (tough) Bandits there, but I would just just run away from them. There is also a large number of chests throughout the city, and looting them does NOT get you into trouble. Finally it has a number of Merchants who you can buy items off, including Bear and Elephant hides to convert into Thick Hide. However, they are expensive and you dont get much for your money.
3) Convert regular Hide at the Armourers Bench(!?): I honestly didnt know about this until this morning. But apparently the Armourers Bench has an option to convert 4 Hide & 1 Twine into Thick Hide. Same can be done with any Bear, Elephant and Rhino hides too. Cannot confirm this personally. This would be the safest way if you are still a bit unsure about an expedition yet. Either way if you havent build one yet, spend some Feat points on a Skinning Knife, as it will net you a lot more hides than an Hatchet or Pick.
Whether you mount the expedition now or not, both areas are great areas to visit when you are feeling ready, be it now or a bit later down the track. Just keep a Bedroll or 2 for mobile spawn points, and a Bed back at home, so that if you feel youre in over your head, you can bail easily.
PS- here is a great map of the Exiled Lands if you dont already have one. Sorry for the wall of text.
