Dota – I can’t see Shadow Demon and Warlock’s Golem in DotA

Note: I haven't played DOTA in a few patches...

Enchantress biggest weakest are nukes because of her little HP
You said you enjoy Nevermore, your best bet would be too just stay out of her range during the lane, and just last hit appropriately...focus on not dying to build up your creep count (which gives you damage) at lvl 3-5 you could start using your long and mid range nukes to last hit+harass the Enchant, and disengage if she wants to fight. This will keep you at high health and her at medium, giving you a significant lane advantage (with three nukes all it takes is one good rune to kill her at medium life). When you do engage dont attack until you have used all your nukes, She has a move that slows you and if she decides to run you wont be able to chase if you attack her. If she ever procs her healing item, just back off and pop a clarity, then harass a litte more aggressively while its on Cooldown, this will force her to heal at well, giving you an EXP advantage.

Be sure to use chicken early game to keep mana/ life in good shape so you dont have to leave your lane and get boots before her so you can chase when you go in for the kill. If she is rushing the +25 INT item, you should have a significant early-mid game advantage with items, big enough to kill her a few times and come out on top.

Non Nevermore specific tips:

• Nukes > Stuns when it comes to Enchant since attacking her will slow your hero.

• You usually have to kill Enchant in 2 bursts, 1 to get her to pop
  heal, then another to kill.

• At the start just last hit and attack her only when your creeps are there

• Keep good control of runes during early-mid game

• Use chicken so you dont have to goto town and heal (meaning you will always be gaining exp)
• Keep an eye out for Enchants chicken, your long range nuke means you can kill it without even going up ramp sometimes

Hope this helps and be free to comment with any questions

Some of the most noticeable changes that pertain to League of Legends:

• Champion selection is limited to the "free to play" champions (which are rotated on a weekly basis) or the ones you have purchased using in game points (Influence points) or real life money (converted into Riot points).
• Maximum level is 18. With the exception of (as of writing this) 2 champions, Udyr and Karma, this gives your Q, W, and E skills 5 levels, and your R ultimate 3 levels. For Udyr, as he has no true ult, but rather 4 basic skills, you could have a 5 5 5 3 setup, or a 5 5 4 4 setup, or any combination therein. For Karma, her ult is given at level 1 and never levels up, giving her Q, W and E skills 6 levels each.
• No denying. This includes towers as well as creeps/minions. You can still deny by keeping enemy champions out of the kill radius / prevent them from last hitting, but there is no "auto-attack your own minions" to deny.
• No gold loss on death.
• Towers hit a lot harder and do more damage to you the longer they've been hitting you, making early tower dives a lot riskier and making towers much safer to defend against.
• You can kill the enemy base/nexus without having to kill the 3 inner lane turrets. You still must kill the 2 nexus towers first, however.
• The ranged/melee barracks have been merged into a single building called an inhibitor, and instead of bolstering the melee/ranged minions in that lane when destroyed, it instead makes a single, powerful melee unit spawn with every wave. Inhibitors respawn over time.
• There are far fewer "active" items (click to use) and the focus is more on increasing your passive stats.
• Every champion has a passive ability that is somewhat integral to their playstyle or their character flavor. These passives are always active and require no skill points. For example, the champion Zilean increases all allies' experience gain by 8% always. A more active example would be the character LeBlanc, who spawns a mirror image whenever she drops below 40% HP (occuring at most once per minute).
• There is a 3v3 as well as a 5v5 map, meaning there are two separate meta-games to identify (though most people play 5v5).
• Some of the larger neutral creeps provide passive buffs that provide a visual effect as well as a bonus to attributes. For example, the Golem buff provides mana/energy regeneration and cool down reduction.
• There is a large neutral creep called the dragon that provides teamwide gold and experience. This is often contested through the mid-late game and is a prime target for jungler champions to kill.
• The "boss" neutral creep (Baron Nashtor) does not provide an item (like Token of Life), but rather teamwide gold/exp and a passive buff that greatly increases health/mana/energy regen as well as additional attack damage and ability power.
• You get to choose 2 additional "Summoner Abilities" that are universal regardless of what champion you pick. Some examples of these are Ghost (temporary speed boost and unitwalking), Flash (short range teleport), Ignite (scaling damage with a DoT and reduced healing/regen component), and Clairvoyance (short cooldown, small radius map reveal). There are others too, of course.
• No river runes.
• You may passively increase your champions' stats by purchasing "Runes" outside of the actual in-game interface. These runes are purchased using points you earn by playing games (winning or losing).
• Additionally, you may increase your champions stats / enhance your "Summoner Abilities" / provide passive effects through the mastery system. The mastery system is a simplified version of a talent tree (akin to Diablo 2, World of Warcraft, etc.) with points being earned as you level your summoner (your account), which is done by simply playing games.
• Ability to return to base (free, no need to buy it, no item slot taken, no cooldown)
• Improved juking - instead of sneaky paths between trees there is "brush" (bushes/grass) system - brush blocks line of sight of those outside it and provides bonuses to some champions/heroes
• Map is symmetrical with the exception of the placement of the Dragon and Baron "boss" creeps.
• Shields system - damage shields are dynamically displayed as a gray extension of the healthbars. Purple extensions indicate magic-only shields.
• It's possible to bind smartcasts (cast instantly on keypress on the area the cursor is hovering over, not on an additional mouse click)
• No secret shops or outposts. All items are purchased at the base shop.
• The Shop's combination items are displayed in a tree, making it easy to see which items combine into what.

I'll add more as I think of more. Hope this is a good start for you!
