WitcherVerse.addLiquidity(uint256,uint256) (#695-708) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,lpAddress,block.timestamp) (#700-707)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

WitcherVerse._transfer(address,address,uint256) (#573-635) uses a dangerous strict equality:
- allowedTxAmount[from] == 0 && sellIntervalStart[from] == 0 (#592)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

WitcherVerse.addLiquidity(uint256,uint256) (#695-708) ignores return value by uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,lpAddress,block.timestamp) (#700-707)
