DRACHENLORDToken.swapAndCharge(uint256) (DrachenLord.sol#286-300) performs a multiplication on the result of a division:
-liquidBalance = tokenBalance.mul(_liquidityFee).div(_liquidityFee + _BNBFee).div(2) (DrachenLord.sol#289)
-bnbForLiquid = newBalance.mul(liquidBalance).div(tokenBalance) (DrachenLord.sol#294)

DRACHENLORDToken._transfer(address,address,uint256) (DrachenLord.sol#226-284) uses timestamp for comparisons
Dangerous comparisons:
- overMinTokenBalance && ! inSwapAndLiquify && from != pancakeswapV2Pair && swapAndLiquifyEnabled && block.timestamp >= lastSwapTime + swapCoolDownTime (DrachenLord.sol#260-264)
Ownable.unlock() (Ownable.sol#49-54) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 0 days) (Ownable.sol#51)
Avoid relying on block.timestamp.

DRACHENLORDToken._transfer(address,address,uint256) (DrachenLord.sol#226-284) compares to a boolean constant:
-require(bool,string)(presaleEnded == true,You are not allowed to add liquidity before presale is ended) (DrachenLord.sol#235)
DRACHENLORDToken.swapAndCharge(uint256) (DrachenLord.sol#286-300) compares to a boolean constant:
-require(bool,string)(success == true,Transfer failed.) (DrachenLord.sol#298)
Remove the equality to the boolean constant.

DRACHENLORDToken._previousBNBFee (DrachenLord.sol#29) is set pre-construction with a non-constant function or state variable:

DRACHENLORDToken._previousLiquidityFee (DrachenLord.sol#32) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
